I have Civ 3 complete, and I was just wondering which patch I download. Anyone know?

None. Civ 3 Complete comes with the basic (vanilla) game and both expansion packs (PTW & Conquests) and is fully patched. If you start a game of Conquests and look in the lower left corner of the main startup screen, you should see 1.22. That's the latest Conquests patch.

OK thanks! :)
