I've never once played any game ever on any Xbox system.
I'm obviously aware of the aforementioned games, but I'm not too savvy on what other games are worth my time(also interested in Alan Wake & Witcher 2) as I still prefer and will mostly play my PS3. So this is where I turn to you, CAG! Please give me examples of games *that can only be found on 360, of course* that I should play that can also be found on the cheap, be they retail or XBLA. I enjoy pretty much all games, except generic FPS' & Strategy games.
