Civilization Revoluton for the xbox 360.

Really good streamlined version of Civ, cartoony feel, faster paced (games take 2-3 hours on the Chieftan rather than 2 days) but still a lot of fun. Some of the things in the eras are a little broken (Greek Hoplites can nearly defeat tanks when they are defending a city!), but other than that, it's definitely worth playing if you're a fan of Civ.
