I picked PS2. Can't go wrong with Final Fantasy X, Kingdom Hearts, Silent Hill 2, etc.

Anyway, hey you can't put Gameboy Advance and Gameboy Advance SP on there. They're the same system, just put Gameboy Advance only. Sure one lights up and looks different, but they're the same. That's like putting 'canned Pepsi' and 'bottled Pepsi' under a "What's your favorite kind of soda" poll.

Hehehe.
