Before I had problems where I had to uninstall and re-install Civ 4, I had a mod that gave me another option for length of game. It was "marathon", I believe, and was something like 1000 turns. I know I got it from here but I can't find it again. Anyone know where it is?

hm, isnt marathon speed a vanilla civ4 speed option after the 1.52 patch?

Otherwise Sevos mod (for one) balance the martahon speed better.
