Recently grabbed RockSmith for PS3 and all my drawing/painting productivity has nosedived. It's a pretty decent shot at bringing some form of entertainment to practicing guitar. And while it's far from perfect (game has some serious UI flow issues, as well as clunky load/save times) it's definitely a good first step in the right direction. I'm pretty terrible at guitar, so anything that gets me excited to practice it 2-3 hours everyday is a pretty satisfying purchase. Also being able to actually play Muse's 'Unnatural Selection' is a pretty big rush.
