Sure, it's coming way after I promised it, but here it is none the less.
Mists of Pandaria - I'm currently taking a break from WoW because I'm tired of farming in games (ironically, I love the little farm you can get in the game now). But a great expansion! I'd be more interested if I had a good raid team/schedule, but in the absence of that. I'm ok without playing for now.
Starcraft 2 - I managed to get a feel of being more involved in the game this past year. Great game. Great community. Expect more great things to come.
Dungeon Defenders - I got freaking hooked on this for a couple of months! Still a great way to burn a few hours.
Guild Wars 2 - Content patches are coming out all the time for GW2. You should definitely take a look if you're in the mood for a good MMO w/o wanting to pay a subscription.
Age of Empires Online - Still fun, but after playing SC2 the gameplay itself feels slow and stale.
Punch Quest/Ski Safari/Road Trip 2 - I love these side-scrolling runner games. Extra props to Ski Safari for having the catchiest music.
Amnesia: The Dark Decent - Aubrey and I finally got brave and started playing through this game. And then we got a big tv. And then we played it on the big tv. And then we decided we were better off just watching Day9's playthrough. By far one of the creepiest games I've ever played. Great mechanics.
Chrono Trigger/Majora's Mask/FF3(6) - Got these babies on the Wii Virtual Console and I play them on the treadmill. Great multitasking!!
