I've been rotating through a few games lately:
-Wrapped up inFAMOUS 2 on hard mode to get the Platinum.
-Slowly playing through Castle Crashers.
-Knocked out a few more standard goals on The Pinball Arcade.
-Beat the Saints in Super Bowl XLIV as the Colts to get a few more trophies in Madden 11. Only two more trophies until the platinum.
EDIT: Got the platinum.
-Playing the daily challenges in Rayman Legends to unlock the last level of awesomeness. I should be done in about 3-4 months.
