What are some good RTS games?

Have you ever heard of Civilization Revolution? I really want that game bad. Apparently it's a game where you get to pick from a list of historical figures like Abraham Lincoln, Caesar, Napoleon etc. and you build up your society by taking over other villages at first and using that land to continue your domination and such. Anyway, it seems pretty cool and I want it for Xbox 360 but it was out for PC first.
