I'm currently playing Just Cause 2. It's like a mix between Spider-Man and TimeSplitters, and it's pretty awesome.
I also play Jet Set Radio, there's an HD version out for that Dreamcast game. In that game, you basically skate around town spraying graffiti.
As for sports games, I play the PES 2013 demo sometimes. I don't give two hoots about the teams anyway (which is what are driving FIFA and PES sales through the roof every year), so I enjoy the gameplay a lot.
In November, LittleBigPlanet Karting will be released, I'm eagerly awaiting that one.
