I am looking for a good video game for my girlfriend for ps3. Any suggestions?

Little big planet

Yeah that one is good, does she like any particular type of games?

What games does she like on other systems?

Uncharted 2 Received a perfect 10 in game informer and that almost NEVER happens. Don't know if she'd like that one though. If you want something with humor get

Ratchet and clank future:tools of destruction

Soul caliber 4/tekken 6 are always good choices

If she likes to sing singstar is pretty fun

All depends what genre she's into.

First Person Shooter - Modern Warfare, Call Of Duty
Racing - Burnout Paradise, Dirt 2, Gran Turismo
Action Adventure - Uncharted, Red Dead Redemption,
Grand Theft Auto 4, Mirrors Edge
Puzzler - Stacker, Echochrome
Quizz - Buzz
