Fun idea. 
PSP: It has Liberty & Vice City Stories, Chains of Olympus, and Ghost of Sparta.
3DS: Resident Evil: The Mercenaries 3D and the Ocarina remake are looking pretty awesome.
Xbox 360: It has Dead Rising, some awesome downloadable games, and the best controller for shooters, imo.
I (have) own(ed) all of those, btw.
