Quickdraw McGraw on 27 January 2009
As I stated in another thread similar to this one, I have a decent gaming PC, which nabs me a large portion of the 360's "exclusive" library, with free online as an added bonus.
Past that, the only titles I really wish I had were some of Live's offerings (ie. Braid, Castle Crashers, etc). (Story-less) Franchises like Gears and Halo never interested me, beyond the multiplayer aspect.
