Based off of Televanni 200yr+ campaign
Let's start with the positives. This mod is stable as a brick I fucking love that. I wish I could pay you all so you could this shit for real because it has a professional level polish you don't see in other games. Kind of wish Steam had not backed down on that. I feel like ya'll deserve some money if you put in the work.
Overall experience: In my campaign I won independence, fought off a Morrowind reclamation invasion, fought off Eastmarch invasion just barely (it was awesome to see them travel some distance, stupid, but still awesome that they did), won a series of internal conflicts that involved me having to declare two baronies independent, subjugated two breakaway baronies from Morrowind that were weak from their independence, married my legitimized bastard to the daughter of the Archcanon who was the commander of the Tribunal forces, took the Mournhold, and then subjugated the entire kingdom of Morrowind with the assistance of the Tribunal Temple. Was also a master seducer with a maimed tongue and a dead vampire hand 10/10 would again.
Positives:
Stable
Portraits (Just fantastic)
Cool Council Abilities
Awesome building tree
Low-scale (I like how their aren't massive 100,000 strong armies. Makes the game feel a lot easier to manage)
Epic map (All the nations, races, cultures, kingdoms, it just looks fantastic)
Divided map (I despise blobs so the interregnum is like a wet dream for me)
Artefacts (not exactly sure why a vampire hand is an artefact but no one else in my kingdom had one so I felt cool and I freaking loved kidnapping other people to steal their artifacts, also is artefacts a typo or is it supposed to be that way?)
Great combat (loved the experienced, hardened, veteran) (Felt like my warrior-king definitely made a difference, won a pitched battle because of him though I lost my second son in the battle, I love that type of experience)
Tons of opposition scheming (at least in my experience)
Great racial traits/professions
Improvements (and some potential bugs)
The tooltips for the council need help or some explanation somewhere - what does improve magickal relations actually do? For heal there was four different options but the only one I got was to increase the disease resistance for gold for a couple years? What are the parameters for successfully fulfilling warlord ambition? I don't know because it doesn't tell me.
Some of the council abilities would not fire, for example despite leaving improve magickal relations on for about a decade I never had it fire once, I fabricated a claim, pressed it but then did not get the claim, the only heal I got despite leaving it on for 7 odd years was the disease resistance, my priest is magical why can't he improve my maimed tongue?
Some of the building tooltips are bugged. Not the majority of them but off the top of my head the hold and shrine descriptions were both broken.
Suggestions
A lot more custom starter characters. For example I think House Televanni should start with master wizard, House Redoran master knight, House Hlaalu master magistrate ect. It feels weird as hell to start the game and have your Archmagister not know a lick of magic, the warrior head of House Redoran be an expert magistrate, and House Hlaalu be journeyman monk.
Magicka obviously needs some work so that it is not OP and the AI can be involved in it. That being said I liked the Magicka system and some of the spells available. I might look at Warhammer Mod for some ideas on balanced magic system. I am not gonna comment too much because I read somewhere you are planning on overhauling already.
More custom titles based off of trait modifiers. I was actually really disappointed to lose my Archmagister title as the Telavanni when I won my independence and declared the Telavanni Kingdom. It worked out since all my line was knights/barbarians anyways so I just role played it out but it still felt weird. If I declare independence as one of the great houses I think they should get a custom titular title.
Morrowind as a whole was boring as hell. I dealt with a lot of backstabbing bullshit from people in my kingdom and I had a great character. High King Rilver The Bloody was an open lycanthrope, terrible stats, was blinded, was a eunich, excommunicated, and spent numerous stints in prison. Despite all of this he was never overthrown or had some declare independence against him besides me. One interesting bit was the tribunal temple taking control of some of Morrowinds territory but I think it was from inheritance. Also nobody bothered invading them, though they were raided a few times.
