They definitely can. I'm sure they could find a good cast of Xbox exclusives but I doubt it would be as varied as the SMB line or even the Playstation all stars. From D-Joe's list, they got a lot of exclusive stuff but they would be REALLY obscure. I think the main problem is that the Xbox started just the previous generation so they haven't had many of their mascots reach that "Legendary" Status like Nintendo's Mario, Link, Metroid and Ness. Sony has a lot of very well known mascots such as Kratos, Rachet and clank, Jak and Daxter and Sly and even those are fro mthe previous gen. The point being they haven't developed as many mascots as Sony or Nintendo. That doesn't mean their games are unoriginal or not memorable, but the Xbox is relatively "too" new at the moment, IMO. I don't see them doing a game like this anyways now that Sony jumped on the genre.
