Civ 4 bts 3.19 + C2C
http://forums.civfanatics.com/showthread.php?t=288570(seriously the level of detail in this one is downright autistic, it has everything rise of mankind has (e.g the revolutions stuff and combat improvements which are pretty cool) makes every age (including the new batshit caveman age) last actually more than 10 seconds and thus drastically more content than Civ 5 has at present in any format. )
Gaem on?
Gotta warn you, I play a mean Brennus.
Also has the advantage over most games the forum can play of being able to switch between play by email mode and everyone playing at once. Also the game is so old now, pretty much anything can play it.
