I havent commented on this mod much considering how much time i've played it. I think its great, and i hope you guys continue into R2 in the future. I'm sure a few of these may have been brought up and i just overlooked them, so just ignore if thats the case. Anyway, after a few campaigns.. probably about 1000+ turns here is what i've noticed.
1. [U]Mountains/Paths[U]: While the map may be completely accurate, for game sake purposes there are a few areas that really constrain the ai from war/expansion or just from being blocked into an area. For the locs in this list I would suggest they be made into a path.
337,157- there seems to be general pathing trouble in this area, sometimes a unit will move thru, other times it will show a path thru but stop.
262,379- every game played the Tyrrhenians gather 6+ stacks around this area. Possibly because the path slightly to the NW has a settlement and the ai feels blocked.. even at war. /shrug
The large amount of still 'rebel' territory from Album Intimelium to the NW into Gaul, and into Boii homeland NE of where Cenomani tribes occupy seem to have few mountain paths aswell and may create more problems later on. These are just suggestions that may clear up a few ai hiccups.
2. Population growth: Mainly the factions that have mountain/plains herding suffer from poor growth. I've played Samnite and i think Umbrians or Sabine maybe and its near impossible to get last tier settlements. 250+ turns and none. I just cheat to get around it. Suggest keeping income the same but adding a few % to the growth bonus.
3 Diplomats: Most of the diplomats in the game seem to gather in the SE tip of Italy just below Uzentum. Most likely they are trying to open diplomacy with the philosophers. Others mods like Rule Britannia and Last Kingdom deal with this by adding a diplomat for that faction. That may be the only way to deal with that. /shrug figured I would mention it.
4. Culture Conversion: Last tier only conversion for some cultures makes it a strain on the budget having to garrison extra troops in places you've conquered.
5. The dreaded campaign_ai_db: This is more of a question since most expansion/war/diplomacy problems are resolved by this crazy(I just hate to stare at code) file. I never played the first PI so i dont know if you guys plan to set this up or if you intend to leave the game as a basic sort of FFA?
There are very few problems at all with this mod. Its put together very well!! I've customized the EDU a bit for myself as i like slower/longer battles, but thats it!
I'm looking forward to what you guys release in the future. I hope you put in the Illyrians, they are quite a fascinating near dual culture society during this time period.
