alright. Apparently, I'm supposed to the "BETTER AI" in the score breakdown with it installed...but I don't. I put the CvGameCoreDLL.dll file in My Docs/My Games/Civ IV/CustomAssets.

I have vanilla Civ IV version 1.74

Civ no longer reads cvgamecore.dll from custom assets. You'll have to copy into in the regular assets folder or create a mod folder for it.

I have vanilla Civ IV version 1.74

Better AI was written for vanilla v1.61 and warlords v2.08. Trying to use it with vanilla v1.74 may well result in strange things happening. :crazyeye:
