When you finish your next game and if you want to try this BuffedAI mod I'll upload the latest version. There has to be at a bit of interest from at least one CivFanatic to make the effort worth it. I like it because instead of giving the AI heaps of free techs etc, Buffed AI just gives the AI proper per-era bonuses and also makes combat a lot harder. I just tried it out and on prince difficulty the AI won science on turn 350 and I had to build a lot more troops to make conquest work. With the offensive bonus the AI gets, it's really nice for the first time to experience my frontline having to retreat because the advancing enemy frontline is actually too strong to attack. I'm normally an immortal player without this mod.
