Hello and welcome back. Mare Nostrum will be upon us very soon so I will take this last dev diary before release to show some extras and the 15 new achievements which will be part of the 1.16 patch. With Wiz safely banished to the furthest reaches of space to make friends with Blorg, I am free to ensure there are no more Eastern Roman Empire related Achievements.
The 15 new achievements, which some clever cookies may have seen before are:
- Mare Nostrum: Restore the Roman Empire and own the entire Mediterranean and Black Sea coast lines.
- Kuban Cigars: As Kuba, own or have a subject own Havana and be the world’s leading producer of Tobacco.
- Kushite Restoration: As a Nubian culture nation, own the entire Egyptian region as core provinces.
- The Fezzan Corridors: As Fezzan, control at least 90% of the trade power in Tunis, Katsina, Safi and Timbuktu.
- Victorian Three: As Basoga, Buganda or Karagwe, reach administrative, diplomatic and military technology level 32.
- The Animal Kingdom: As Manipur, unite the Bengal region and convert it to Animism.
- Golden Horn: As a Somali nation, fully own the Horn of Africa region and have a monthly gold income of at least 50 ducats.
- Kinslayer: As Tver, Yaroslavl, Ryazan or Odoyev, eliminate all other Rurikovich nations without changing your ruling dynasty.
- Choson One: As Korea, own or have a subject own all Shinto, Confucian and Buddhist provinces in the world.
- Sailor Mon: As Pegu, have at least 100,000 sailors.
- The White Company: Hire your army out to both sides in a war and fight in a battle against your former employer.
- Networking: Have 100 point spy networks in 3 rival nations.
- Time Bandit: Successfully steal a map from another nation.
- With a little help..: As Ragusa, lead a Trade League of at least 5 nations and guarantee the Ottomans’ independence
- Just Resting In My Account: Corrupt the officials in a rival country

Going hand-in-hand with one of these achievements, we have added one of the longest requested formable nations: The Roman Empire. It is no easy task to perform, requiring Christianity or Paganism and ownership of the regions of Italy, France, Iberia, Balkans, Anatolia, Mashriq as well as certain key provinces, but doing so will allow you to recreate the thousand year empire and grant you the new unique culture of Roman.

Forming Rome is a free feature, available as part of the 1.16 patch.
Next up is Timeline, a new Mare Nostrum feature

At any point through your campaign you can hit the new timeline button next to the date and observe how the world has evolved throughout the years. Watch as empires rise and fall and re-live how your own nation rose to its great heights (hopefully)

Opening Timeline will bring the map back to how it was at the start of your campaign and then you can choose at what speed to run through the world's history. You can pan all over the map during this timeline, so while the Big Blue Blob takes over Europe you can admire infighting new world natives or see which of the Daimyo's made Japan theirs.
