Wake me up when OpenCiv4, but only when there's an option for smart AI rather than boosted fake AI.
I remember losing 6pm to 3am playing civ 4 one time. One more turn...
(But I'm not sure what I need openCiv for... the steam game is good. Maybe its just useful for the long term.)
Civ4 is super cheap on Steam BTW
I would love to see someone use modern machine learning techniques to make a kick ass Civ AI.
