Least: Wii
It's by Nintendo so I love it, wait....
New least: PS3
It has God of War 3 and Little Big Planet, the only reason for me to get a ps3 when I see it for $100 bucks.
Least Handheld: PSP
Crisis Core: Final Fantasy VII, the reason I got it in the first place. And the psp was better than I though it was gonna be.
