Going through way too many games atm:
Uncharted 2 - Better than the first, very very fun ride so far. Might be my favorite game that I've played for my new PS3.
MGS4 - I'm a fan of the series, so I've been interested in finally finding out what happens plot-wise in this game, but goddamn the frequency and length of cutscenes is starting to bug me. Two acts down, both of which were enjoyable but could have been much better if the cutscene to gameplay ratio was higher. Good game though, I like it as much as the rest of the series.
Littlebigplanet - After much bugging from PS3 owning friends, I finally picked this up. It's a fun little platformer, and I found quite a few interesting and fun levels that people have created. I enjoy the multiplayer and solid platforming, but I don't have enough patience to create a level like that. Maybe one day.
Bayonetta - Since all my backlogged 360 games got put aside once I got my shiny new system, I never got a chance to play this but I decided to start it up since I missed my 360 controller. Love love love the battle system, truly fantastic stuff.
Infamous - Sucker Punch doesn't let me down. I've been fooling around with side missions and stuff and I'm having a blast.
