At the mo,

Monster Hunter!!! .hora.
And Monster Hunter only LOL Freedom Unite and Portable 3rd which I must say is seriously good

Freedom Unite I've racked up about 420hours. . .O_O

My favorite of all time is The Legend of Zelda Ocarina of Time!

Black Ops is the game of the moment for me. Favorite game of all time... It's got to be the original Legend of Zelda. I can still pop that game in and start a new quest and enjoy it.

Metal Gear Solid Peace Walker!

I have mentioned only the games that I'm willing to replay at any moment and will (probably) continue to play them from time to time, even after a few decades.

Favorite series (most to least): Half Life (I'll be replaying it even after 50 years), Devil May Cry and Mass Effect.
Favorite games: Metal Gear Solid 4, Tron 2.0 (for a computer geek like me, this game is heaven), Heavy Rain (OMG, I'm speechless about this title... simply unique), Castlevania: Lords of Shadow (haven't played other castlevania games, I feel like I'm missing a lot),
