I gotta admit, if I didn't own a 360 now I don't think there are any games that I would buy the console for, as in a single game.
I remember feeling quite different about it though with the PS2 for example, where there was MGS, GTA3, Tekken...I really wanted to experience those games.
Not sure if its an age thing, or the lack of original deep gaming experices that draw you in?
I'm sure it is age to a degree, but hard to put it all down to that.
The only game that has truly felt like "the good old days" would be Dead Rising...loved it.
