Some of my favorite releases:
Bioshock (Not as deep as system shock by any means, but the setting was great and well delivered)
Madworld (Man this game is a HOOT specially with a couple friends around to go 'WTF DID YOU JUST?!...')
Team Fortress 2 (Some of the best character design in a looong time, and its in a MP FPS!)
Super Mario Galaxy (Level design was pretty amazing on some of the worlds)
Mass Effect (I wasn't a HUGE fan of the story or characters, but the universe they created was deep and flavorful)
Smash Brothers Brawl (Great party fun, wish the online was better though)
World of Goo (Amazing game, if you haven't played it yet go check it out!)
Portal (Of course we all loved this game)
I'm sure many of you have noticed a distinct lack of RPGs, especially cRPGs on that list... wellllll I find that there simply hasn't been that many amazing RPGs in the last few years. There has been a few good ones but nothing that made me go 'wow...', and as for cRPGs well there has been a HUGE drought of cRPGs in the last few years with only a few out there, and many of them buggy and boring IMO..
What about you folks? What are you into these days?
**edit** forgot to mention: Anything by Tell Tale games is amazingly fun, not always long or particularly deep, but ALWAYS fun.
