I say once again, this is a great mod. I finished up with the Maya and am almost done with the Tupi, both Regent (Maya was diplomatic, Tupi looks to be cultural). Played through the Nomad and Kingdom eras, gave everyone techs so they'd build as much as possible, didn't crash or boot out or anything. I can't seem to get to the European Influence era though, no matter what I do (government, scientists, etc.) the tech progression is too slow to get there before I win.
Some things that happened in my games: South American civs and Sioux (in both games) were hyper-aggressive, going on rampages through other ones (I was included in this category as Tupis; in the first game the major aggressor was the Mapuche). For the S. American civs, I think it has to do with having the Chasqui scout in the first turn--I killed off three civs in the first 10 turns, running around like crazy. The AI likes to march its 0/1/1 braves around rather than use to guard cities. I don' t know why Sioux were so aggressive in both games, but were the first to attack neighbors (besides me, eheheh).
I also think now that the mod is oriented (intentional?) so that civs SHOULD NOT kill each other off--if you play your turns right, you can get the AI as well as you to research different things and trade away, making up for tech/time lag. In my Maya game, I had to keep several civs around just for this reason. My Tupi game ended up with just me and the Sioux, on two different continents unreacheable until Maps, with each of us killing all other civs fairly early in the game. What is the advantage of a non-Blood Cult government? (besides paying for improvements)
Anyway, just wanted to give you some feedback on the game. Great work, y'all, please keep it up.
