and it does that very well. the problem I have is once I hit the renaissance, industrial, and modern eras the game slows down to an incredible crawl, and it's not due to my slow turns(I am quite slow), it's the AI's turns that take forever. each era multiplies the length of time it takes to finish a single turn. I'm not sure anything can be done about this since the mod adds so much content, but having to start a new game just to get the sense that you can actually play it is not exactly fun. As much as I enjoy the starting era, I would like to finish a game now and then. And that's something I haven't yet done, despite starting plenty of them. I just get too frustrated with the length of time spent and wind up starting a new game.
Post a recent save (after turn times get turgid) and I'll profile it and see if anything leaps out at me.
