Looking to see what I want to buy next....I've pretty much only got Sports games right now, plus Gears and Halo 2. So I need some more non-sports games. A driving game cuz the wife likes those. Preferably one that is easy to just pick up and play for a newcomer, but not boring for a more experienced gamer. Something she can just hop on and race me. I've heard Forza 2 is good, but what games are there where you can do some track racing, street racing, and off roading? Or am I asking too much? Then.... Which do you prefer of the following and why... GRAW 1 or 2 Rainbow 6 Vegas Lost Planet Oblivion IV Others...?
