About 36 mods, but most of them are extra civs. The mods I use that change gameplay are:
Mercenary Army Expanded, Great Prophet Names, More Great Works, Art Building Tweaks, Gilbratars reef and krakatoa fix, city limits, Faster Aircraft Animations, Corperations, Citystate diplomacy, Civ IV Diplomatic features, less warmonger hate, and The religion beliefs expansion pack.
are you noticing a lot of crashes?
