I'm planning of buying CIV 3 with Conquests, but I wonder if then I gonna have the civs from PTW, too? And is it possible to change the game's language to english? :shakehead

Conquests has everything that PTW has, and then some. ;)

It also has a multi-language installer, so you can install into your language no matter where you bought the CD. However, it does *NOT* convert other civ3 files to English.
