I think everyone can agree one of the best parts of a new patch is seeing which nations get their own NI sets. And one of the most frequent topics in the suggestion forums are suggestions for said new NIs. Unfortunately, they can be difficult to find, and can fade away pretty quickly. Hence this thread.

As I recall there used to be a thread similar for this a while back, but since I can't seem to find it, I've created this; a new NI compilation thread, where I'll try to upload any suggested NI sets I see for nations that do not yet have them for convenience's sake. If there is an Idea Set of yours for a nation that does not have an unique NI set, or if I missed one of yours, please; feel free to post.

Edit: Also, please try to keep it restrained to only tags that are already in game or have been confirmed are being added.


At the request of @Trin Tragula, I’ve composed an index of this thread that I’ll do my best to keep updated. I’ve separated it into NIs for countries that already have them (which may or may not have been influenced by the ones in this thread) and ones that don’t, and then alphabetized them for ease of access. Author will be put in parenthesis.

This very belated update to the list was courtesy of @Aquamancer, who did the legwork in updating the thread to match the current situation of NIs ingame, as well as to make it more visually appealing.

I would be much obliged if someone could make an index of sets in this thread :)

Certainly! I'll get on it later today. Would you like me to separate it into sets that have already been accepted and ones that are still up for grabs?
 
Strictly speaking only sets for countries that don't have any are needed by me but it might be easier to list them all? It's up to you :)
 
All right, I apologize for the delay Trin, but I got it up; I've attached the index to the first post for ease of access.

Going through all the NIs has astounded me as to the amount of NIs that have been made for HRE OPMs.

NI patch confirmed :eek:!
On a more serious note: I have made an alternative NI set for Nuremberg with replacing one idea with the ambition, so what suits you more.
Hello, here my National Idea sets for the Austro-Bavarian region taken from this thread (also contains NIs for the unimplemented Bamberg and some other drafts).
The thread also contains supplementary informations if one is interested.

  1. Traditions: +20% garrison size, +10% province trade power
    Reason: Nuremberg is well known for its castle and enormous walls. Also, the
    position between Frankfurt and Prague, Bavaria and Saxony made Nuremberg an
    important centre of trade.
  2. Imperial Regalia: -1% prestige decay, +1 diplo rep
    In 1423, Nuremberg was granted the Imperial Regalia to everlasting
    preservation by emperor Sigismund. Now that we have brought them here hidden
    in sh barrels to prevent their theft, let us show the world our importance and
    eternal glory!
  3. Nuremberg Castle: -10% land maintenance
    In 1427, our city's council bought the ruins of the Burgrave's Castle from the
    Hohenzollern. Now the whole castle belongs to our city, so we will renovate and
    then use the barracks and the Imperial Stable to accomodate our own soldiers.
  4. Nuremberg Chronicle: - 10% admin technology cost
    Among our citizens are notable scientists like Hartmann Schedel, writer of a biblical
    paraphrase and world history. This chronicle named for our city is sought across
    all of europe. We truly have profound knowledge of the whole world!
  5. Rostbratwurst: +10% production efficiency
    Our sausage is among the best and most famous in the Empire and already has
    centuries of tradition. Let us regulate the size and the price of our Rostbratwurst
    in an order of butchers to increase the productivity!
  6. Franconian Centre of Reformation/Renaissance: -5% idea cost
    Nuremberg's citizens always were open to new ideas and already follow the new
    faith form the north. Thus we should embrace the protestants, and found a school
    in honor of the reformators.
  7. Christkindlesmarkt: -10% stability cost
    Ihr Herrn und Frau'n, die Ihr einst Kinder wart,
    Seid es heut' wieder, freut Euch in ihrer Art.
    Das Christkind lädt zu seinem Markte ein,
    Und wer da kommt, der soll willkommen sein.
  8. Peace Banquet: +1 diplo slot
    After the signing of the Peace of Westphalia, the peace executional congress assembles
    in our city. We should use this opportunity to make contacts with all
    European nations.
  9. Ambitions: + 10% global trade power, +10% trade range
    The Nuremberg exchange was founded to be more inuential in trade even further
    away.

  1. Traditions: +20% garrison size, +10% province trade power
    Reason: Nuremberg is well known for its castle and enormous walls. Also, the
    position between Frankfurt and Prague, Bavaria and Saxony made Nuremberg an
    important centre of trade.
  2. Imperial Regalia: -1% prestige decay, +1 diplo rep
    In 1423, Nuremberg was granted the Imperial Regalia to everlasting
    preservation by emperor Sigismund. Now that we have brought them here hidden
    in sh barrels to prevent their theft, let us show the world our importance and

    Nuremberg's citizens always were open to new ideas and already follow the new
    faith form the north. Thus we should embrace the protestants, and found a school
    in honor of the reformators.
  7. Nuremberg Exchange: + 10% global trade power, +10% trade range
    For centuries we have been a centre of trade in the middle of Europe leading to
    wealth and prosperity for our citizens. To secure and improve our trade position,
    we will establish the Nuremberg Exchange at our capital's market place, so that
    tradesmen from Antwerp to Venice and from Dansk to Lyon will head to our city.
    A public balance and public exchange rates will prevent and solve conicts between
    all merchants.
  8. Christkindlesmarkt: -10% stability cost
    Ihr Herrn und Frau'n, die Ihr einst Kinder wart,
    Seid es heut' wieder, freut Euch in ihrer Art.
    Das Christkind lädt zu seinem Markte ein,
    Und wer da kommt, der soll willkommen sein.
  9. Ambitions: + 1 diplo slot

Going through all the NIs has astounded me as to the amount of NIs that have been made for HRE OPMs.

I appreciate your work! This thread has lead to many new implemented NIs. On a side note: Moravia has gained NIs in the last patch (I think the ones proposed here), so you could move them to the taken section.

Thanks for pointing that out, I've fixed it.

Top notch work as always, thank you.
 
Just posting to inform I've updated the Siberian NIs I posted long ago; nothing spectacular, but I felt some changes ought to be made to make them more balanced/flavorful.

Yukaghir should still have the weak Siberian NIs though, they do not deserve to be good ever.
 
Delhi Ideas, courtesy of @JKiller96, retrieved from here:


Tradition 1: -15% Core Creation Cost (Due to having ruled the Indian Subcontinent before)
Tradition 2: +3 Tolerance of Heathens (Obligatory tolerance for Hindus)
Idea 1: Might of Islam- +2% Missionary strength
Description: The Quwwat-ul-Islam Mosque was built by the founder of the Delhi Sultanate, Quṭb al-Din Aibak, continued by his son, and was built over the remains of Jain and Hindu temples, like many other mosques during this period in Hindustan.
Idea 2: Development of Urdu- -5% Administrative tech cost
Description: Urdu was developed out of the mingling between Hindustani and the languages spoken by Muslims, Arabic and the Turkic languages, and acted as a sort of communal language for Hindis.
Idea 3: Turkic and Afghan Dynasties- +10% Cavalry combat ability
Description: The Turkic and Pashtun rulers have a long history of using cavalry in their conquests and in their nomadic lives. Through the Turkic Sayyid and Afghan Lodi dynasties we are apart of this heritage.
Idea 4: Founding of Islamic Cities: -5% development cost
Description: During the late middle ages and age of discovery, many great Islamic cities were founded, such as Agra, and the repopulation of destroyed cities such as Lahore.
Idea 5: Tombs of the Sultans- -10% construction cost, +0.5 yearly prestige
Description: Delhi and the surrounding areas were the focus of monumental building projects during the Mughal era. Tombs of the Delhi sultans tended to elaborate, and tombs such as the Taj Mahal were even grander.
Idea 6: Subdue the Rajputs- -10% stability cost
Description: The Islamic rule of Delhi over the Hindus of Rajasthan tended to draw rebellions that led to the deaths of previous incarnations of the sultanate. Instituting better local governorship and putting down rebellions efficiently, we can safely rule this area for the time being.
Idea 7: Indian Salt Peter- +10% fire damage
Description: The Indian salt peter trade helped European powers supply their armies with gunpowder. Using the production of salt peter in India, we can truly become a Gunpowder Empire.
Ambition: +1 accepted cultures
 
I know Rome already has it's national ideas, but while they are good, they don't feel like enough of a reward for free empire rank (which you should already have when you form them - it requires more than 1000 dev!), have your culture changed to a worthless one, and a small prestige boost. I'd argue Rome's ideas are WAY too similar to Italian ideas, for a much harder formable. Being the hardest formable in the game (except Sokoto, but we don't talk about that), they could get a small boost around.

This is mostly a minor buff. Do remember all of those ideas are likely already unlocked by the time you form it.

Tradition 1: +5% Discipline -> unchanged
Tradition 2: +1 Legitimacy -> +1 Yearly Navy Tradition

Pax Romana: -1 Unrest -> -10 Years of Separatism (rome would integrate it's citizens well; separatism was not common and most loss of land came from invasions)
Legacy of Rome: +2 Diplomatic Reputation -> +2 Diplomatic Reputation, +1 Yearly Legitimacy
S.P.Q.R.: -20% Stab cost -> -15% Stab cost, +10 Max Absolutism (the nation is roman EMPIRE; during it's empire phase, rome was pretty centralized)
The Roman Legions: +15% Land Force Limit, +10% Infantry Combat Ability -> +20% Land Force Limit, +10% Infantry Combat Ability
Roman Architecture: +20% Production Efficiency -> unchanged
Imperial Bureaucracy -> Citizen Army: +10% National Tax -> +0.5 Yearly Army Tradition. +10% Morale of Armies
Imperium Sine Fine: -20% Coring Cost -> -33% Coring Cost OR -20% Coring Cost, +5% Administrative Efficiency (deserves more boosts to CCR than Italy, to be fair)

Ambition: +33% National Manpower -> unchanged

Description for new idea 6 "Citizen Army":
The military successes of Rome are mostly credit of a large army of well-paid, highly skilled citizens, ready to defend the greatness of their nation. Those who see the light of Rome refuse to let any vile barbarian challenge it!

Tradition 1: +5% Discipline -> unchanged
Tradition 2: +1 Legitimacy -> +0.5 Yearly Navy Tradition (comes back too)

Did you mean +0.5 Navy Tradition or Army Tradition? +0.5 Navy Tradition is pretty weak in my opinion - most NT bonuses have it at a full 1.

I thought the rest was pretty powerful on it's own and wanted to give this mostly to ensure Rome's fleet - which was quite respectable - to not be easily trashed.

However, good reminder. Given how weak navies are, high navy trad bonuses are hardly too big of a deal.

I edited the post.
 
So after making a call for HRE improvements, I wrote a national idea set for Oldenburg.

Oldenburgian Ideas:
  1. Traditions: +20% fort defense, +10% trade efficiency
    Reason: The city of Oldenburg had a strong fortication for a long time and was
    built at a strategic position for trade.
  2. Kings of Denmark: +1 diplo rep, +20% improve relations
    The House of Oldenburg has ascended to the throne of the Kingdom of Denmark,
    so that we have now powerful allies in our vicinity. As our relatives guarantee
    our independence through their enormous strength compared to our neighbouring
    countries, we can more freely try to enforce new tolls, enforce new sovereign rights
    and conquer more land without fearing a coalition. Furthermore, foreign powers
    will try to inuence the Danish kings through us, which we can use for our own
    benet.
  3. Dike Building: -10% development cost
    We controll only a small amount of land which at the coast gets ooded. Therefore
    we have to build dikes at crucial positions to make more land arable and to connect
    some of our more remote lands with our capital.
  4. Oldenburg Horse: +10 % cavalry combat ability, +10% goods produced
    At rst only an occupation of our rulers, the breeding of horses of the Oldenburg
    breed has developed to a lucrative source of income. Since the Oldenburg horse is
    strong, well tempered and brave, so that it is heavily sought earning us the joking
    title of an "Equerry of the Holy Roman Empire".
  5. Michaelmas Market: +10% local trade power
    We have decreed that a market, the Michaelmas Market, shall be now held every
    year at the end of the harvest season. Five days starting from the saturday before
    Michaelmas Day, the 27th of september, domestic and foreign merchants will be
    able to oer various goods for sale strengthening our trade.
  6. Foundation Abbey Blankenburg: -1 national unrest
    After we have chosen to follow Luther's teaching, we have dissolved our country's
    abbeys of which some stand empty. As the poor and orphans had no longer a place
    to dwell, we have decided to learn from our mistakes and institute a foundation at
    the former Abbey Blankenburg.
  7. Elsether Weserzoll: +10% trade steering
    Although, we were granted the privilege to tari ships passing the toll station at
    Elseth which is the last toll station before the mouth of the river Weser, the
    emperor had to help us to bend Bremens will to accept this toll. Since we have
    to operate many dikes and a lighthouse at the isle Wangerooge, this toll seems
    justied to us. Now, the additional ducats will ll our treasury!
  8. Elevation to a Duchy: +1 yearly prestige
    Ever since, Oldenburg was only a county. But now that we have expanded and
    claimed other land titles, the time is at hand to proclaim the Duchy of Oldenburg.
    Now, we will no longer be looked down by dukes owning less land than we do!
  9. Ambition: +10% naval combat ability
    Reason: Mini-Denmark ambition.

Note: I know that Oldenburg became a grand duchy after the Congress of Vienna, but Peter I. still styled himself as a duke. After Peter's death in 1829 (= not in the game's time frame), August I. was the first to call himself grand duke.

Edit: I think the Anhalt NIs by @Hipster_on_Ice from here are missing:
Anhalt:

Traditions:
+1 Diplomatic reputation (Deeply involved with the diplomacy of Brandenburg-Prussia)
+1 Yearly Prestige (Same house as Albert the Bear, among other notable people in the centuries before the start date)

Ancestral Seat of House Ascania: +1 Yearly Legitimacy
The Princes of Anhalt from the House of Ascania, named after Schloss Askanien, retained possession of the family's ancestral castle from circa 1100 until the abolition of the German nobility following the First World War. While several branches of the dynasty managed to acquire more prestigious titles, including the Duchy and Electorate of Saxony, first Margraves of Brandenburg, and even an Empress of Russia. Despite this, the Anhalt line maintained the distinction of retaining their title through the entire early modern period.

Loyal to the Protestant Cause: +1% Missionary strength vs heretics, +5% Church power
Like many princes in the northern section of the Empire, the princes of the Anhalt principalities remained loyal to the protestant cause despite their defeat in the Schmalkaldic War and the devastation of the Thirty Years War. Though some of their neighbors later converted to Calvinism, the Princes of Anhalt remained resolutely Lutheran. Several of the princes of Anhalt converted after hearing Luther speak at the Diet of Augsburg.

The Unification of Anhalt: −0.05 Monthly autonomy change
The principalities of Anhalt-Zerbst, Anhalt-Plötzkau, Anhalt-Dessau, and Anhalt-Köthen were unexpectedly unified for the first time since 1252 under a single ruler in 1570, Prince Joachim Ernest, following the deaths of his brothers. While the principality was later partitioned again by his children, his unification of the principality allowed him to undertake sweeping administrative reforms, creating the Landesverordnung Anhalts, a single legal code to be used within the principality.

Prussian Clients: +25% Army Forcelimit
Beginning in the early 17th century, many of the Princes of Anhalt acted as commanders in the Prussian army and diplomats on behalf of Brandenburg-Prussia. While Anhalt was nominally a sovereign principality, their longstanding close ties to the Hohenzollerns and institutional involvement in the Prussian army and diplomatic affairs gave them significant influence within the nascent Prussian state. Some of that would come to an end when Prince Leopold III von Anhalt-Dessau later renounced his ties to the Prussian military and announced his neutrality, though his heirs remained involved as Prussian officers.

The Fruitbearing Society: -10% Idea Cost
In 1617, Prince Ludwig von Anhalt-Köthen acted as a founding member and the first president of the Fruchtbringende Gesellschaft, the Fruitbearing Society, the first organization committed to standardizing vernacular German as an academic and literary language. Modeled after the Italian Accademia della Crusca, the organization counted hundreds of members, including a king and a multitude of sovereign princes and other notables.

Der Alte Dessauer: +5% Discipline
Leopold I von Anhalt-Dessau, in addition to reigning as Sovereign Prince of Anhalt-Dessau for over fifty years, was a close friend of the 'Soldier King' Friedrich Wilhelm I of Prussia, a Generalfeldmarschall in the Prussian army, and one of the most renowned drillmasters of his time. Initially Leopold earned recognition in the Prussian army as an able field commander during the War of Spanish Succession, and though he continued to perform well in the field for the forty years afterward, his greatest military achievement was off of the battlefield. The drill techniques that he imposed upon the Prussian infantry are credited as a main reason that the Prussian army became such a dominant force in the mid-18th century. His rigid discipline and unyielding drilling earned him the nickname 'der Alte Dessauer', the Old Dessauer, and inspired a Prussian march of the same name.

Germany's Most Exquisite Garden: −10% Development cost
Leopold III von Anhalt-Dessau is notable as a disciple of the enlightenment and as an inveterate Anglophile. While his enlightened reforms to education, science, and religious tolerance are notable, his most lasting project was the construction and furnishing of the English Grounds of Wörlitz, the oldest and largest landscape garden on the continent. In contrast to meticulously kept French-style formal gardens, landscape gardens were meant to evoke the feeling of an idyllic pastoral scene, with picturesque features and a more naturalistic appearance. The garden has been open to the public since its construction, the Prince convinced of its value as an educational institution for horticulture. The gardens remain in existence today, occupying 55 square-miles in Saxony-Anhalt's Middle Elbe Biosphere Reserve.

Ambition:
−1% Yearly army tradition decay

    will try to inuence the Danish kings through us, which we can use for our own
    benet.
  3. Dike Building: -10% development cost
    We controll only a small amount of land which at the coast gets ooded. Therefore
    we have to build dikes at crucial positions to make more land arable and to connect
    some of our more remote lands with our capital.
  4. Oldenburg Horse: +10 % cavalry combat ability, +10% goods produced
    At rst only an occupation of our rulers, the breeding of horses of the Oldenburg
    breed has developed to a lucrative source of income. Since the Oldenburg horse is
    strong, well tempered and brave, so that it is heavily sought earning us the joking
    title of an "Equerry of the Holy Roman Empire".
  5. Michaelmas Market: +10% local trade power
    We have decreed that a market, the Michaelmas Market, shall be now held every
    year at the end of the harvest season. Five days starting from the saturday before
    Michaelmas Day, the 27th of september, domestic and foreign merchants will be
    able to oer various goods for sale strengthening our trade.
  6. Foundation Abbey Blankenburg: -1 national unrest
    After we have chosen to follow Luther's teaching, we have dissolved our country's
    abbeys of which some stand empty. As the poor and orphans had no longer a place
    to dwell, we have decided to learn from our mistakes and institute a foundation at
    the former Abbey Blankenburg.
  7. Elsether Weserzoll: +10% trade steering
    Although, we were granted the privilege to tari ships passing the toll station at
    Elseth which is the last toll station before the mouth of the river Weser, the
    emperor had to help us to bend Bremens will to accept this toll. Since we have
    to operate many dikes and a lighthouse at the isle Wangerooge, this toll seems
    justied to us. Now, the additional ducats will ll our treasury!
  8. Elevation to a Duchy: +1 yearly prestige
    Ever since, Oldenburg was only a county. But now that we have expanded and
    claimed other land titles, the time is at hand to proclaim the Duchy of Oldenburg.
    Now, we will no longer be looked down by dukes owning less land than we do!
  9. Ambition: +10% naval combat ability
    Reason: Mini-Denmark ambition.

Note: I know that Oldenburg became a grand duchy after the Congress of Vienna, but Peter I. still styled himself as a duke. After Peter's death in 1829 (= not in the game's time frame), August I. was the first to call himself grand duke.

Edit: I think the Anhalt NIs by @Hipster_on_Ice from here are missing:

Thanks for catching that! OP has been updated.
 
So today I have another NI set for a small HRE nation - Saxe-Lauenburg - to add to your list @Grand Historian . It was the hardest nation to come up with new NIs so far - at least for me. Seems like this small northern land was quite unimportant and even more boring.

  1. Traditions: +1 land leader maneuver, -25% unjustied demands
    Reason: Saxe-Lauenburg has many rivers and forests -> maneuver. The unjustied
    demands for Albert the Bear.
  2. Askanian Electorate: +20% improve relations
    After the unsuccessful attempt of Albert the Bear, the Ascanians were enfeoffed
    the Duchy of Saxony by emperor Barbarossa in 1180, because of Henry the
    Lion's betrayal. When in 1296 the duchy was split into Saxe-Lauenburg and Saxe-
    Wittenberg, the long struggle for the Electorate of Saxony began leading to the
    double elections of 1314 and 1349. In both cases the dukes of Lauenburg and Wittenberg
    gave their vote a dierent candidate resulting into a four to four outcome.
    This induced the Golden Bull which granted the Electorate to the dukes of Wittenberg.
    Although the Ascanians of Wittenberg got extinct in 1422, our branch of
    the family was neglected, when emperor granted title and land to the Wettines. If
    we ever want to get to our right, we will have to use every opportunity!
  3. Schlüse zu Bockhorst: +10% local trade power
    Our position between the hanseatic cities of Bremen, Hamburg and Lübeck has
    proven to be benecial for our trage. The Stecknitz canal between Lauenburg and
    Lübeck and its oodgate in Lauenburg called Schlüse zu Bockhorst are two of these
    benets for our trade. Therefore, we have to keep the latter intact.
  4. Eternal Union: -10% stability cost
    Our primogeniture has sometimes lead not only to conicts but also to wars between
    family members. In these situations our territorial estates intervened and
    guaranteed the unity of our duchy. For a better cooperation between themself and
    between them and our dukes, our estates have partnered in the so called Eternal
    Union".
  5. Sachsenwald: +10% production eciency, + 1 combat ability in terrain of capital
    The Sachsenwald was once a primeval forest spanning from the Baltic Sea to Lower
    Saxony, but was reduced to the part in our lands only. Since we don't have any
    other natural ressources than wood, we need to protect our forests through a
    general disposition to guarantee the forests' existence for generation's to come.
    Furthermore, the forest is crucial for defending against bigger foreign powers, as
    noone knows our forest better than we do.
  6. Pledges of Land: -1 interest per annum
    Because of our many claims and the poverty of our land, we often had to take
    loans pledging certain parts of our lands. Our continuing experience with loands
    has lead to us being able to know how to negotiate the best conditions .
  7. Animal Park Juliusburg: -33% cost of reducing war exhaustion
    We need some amusement in our drear landscape. Thus, we have decided to build a
    maison de plaisance and a zoo close to Abbendorf which we renamed to Juliusburg
    in honor of great members of our dynasty. Let us escape the drab monotony of
    everyday life there!
  8. Territorial School Ordinance: -10% idea cost, +1 % missionary strength
    Impregnated with the ideals of the enlightment, we have decided that our subservients
    shall participate, too. Therefore, we will introduce a compulsory school
    attendance for children older than six. They will learn to read and write and get
    visited by preachers to spread the word of god on a weekly basis.
  9. Ambition: +1 diplomatic reputation
    Reason: Getting back the electorate through diplomatic inuence.
