I play very few new games anymore cause most of them suck, so I've gotta try hard and remember what actually came out this year that I gave a damn about...
Portal 2
Saints Row the Third
Skyward Sword
Now, despite the fact that I haven't actually played Skyward Sword yet, it is really the only thing I can include because this is pretty much all of the new games I played (or will play) from this year.
Personally, I found Portal 2 highly enjoyable and actually spent a lot of time playing it, even playing through it several times (co-op, too). SR3, though it does feel a bit smaller than SR2, still feels as though it was worth getting and I've spent well over 50 hours on it already and haven't finished the main storyline yet; that's not taking into account a second play through as a female character to make the alternate choices, either.
I'm sure some might wonder why Skyward Sword and not Skyrim, and the reason is that I refuse to play a game like Skyrim on a console. It doesn't look as nice, it is a lot harder to patch, and the mod support will be pretty much nonexistent on a console. However, I do not have a computer that can play Skyrim (or Portal 2 or anything else made this year) yet. Once I do, I plan on getting it toot sweet.
Also, I actually think SS will be pretty decent. I actually enjoyed most of Twilight Princess, and while I thought the DS Zelda games were absolute shit (for different reasons), I typically enjoy the console Zeldas and am looking forwards to getting it in the next couple weeks.
EDIT: Just remembered that while I didn't play some of the other games like Dead Island and Sonic Generations, I DID watch my cousin play them and wasn't very impressed.
