JSRF already works pretty alright so Im not going to say that.
The game I would be most keen on would be 007:everything or nothing. The amount of varied gameplay and replayability the game offers often make me look back at it, as I play more recent games that makes me think of how repetitive they are compared to what could only be played on an old xbox, ps2 or gamecube/wii.
Also it had coop and whatnot, but this cuould have been xbox live buisness, and an awesome achievement system (Sort of), that awarded you for doing actual creative stuff.
I would also love to put in my strangers wrath or beyond good and evil in my xbox and get to play it, yes. And that psychonauts and halo:CE wouldnt play like shit on it.
