Most played game of 2010 so far?

Silent Hill: Shattered Memories or Uncharted 2

I've played Assassins Creed 2 for about 5 hours, and then Forza three for about 3 so far.

Bordelands (Platinumed it) and MW2.

Demons Souls and Uncharted 2.  Not sure which ive played most just a couple hours of each but probably demons souls

Ghostbusters. Got it for xmas and highly recommend it if you're a fan, and happen to be appropriately forgiving. I can't get enough of trapping ghosts...

I've been playing GTA IV: Liberty City Stories as my sis bought me it for Chrimbo. I'm only a couple of hours into The Lost and Damned but I'm enjoying it thoroughly. 
 
I'm going to dust off the Wii soon and buy Silent Hill: Shattered Memories.

Gears of War 2 because of the XP increase.

Saints Row 2. Tryin' to catch up on some back catalog games.

Modern Warfare 2 is the only game I've played. I'll probably go pick up Uncharted and Creed tomorrow. 

Half life 1 source :D

Altitude.

" I played about half an hour of Shadow of the Colossus....  :P "

Okami is my most played game of 2010 clocking in at 3 to 5 hours. It's either that or Civilization 4 followed by Team Fortress 2.

MW 2 on PSN.

Definitely Grand Theft Auto: Chinatown Wars. Got the PSP version for Christmas. In fact, I think it's the only game I've played so far this year.

Infamous and Rock Band 2 as always lol

Mass effect.

Just beat Borderlands, may head back for another playthrough, may not. 

Half-Life²

So far I have played about half an hour of Fallout 3 and 10ish hours of KH 358/2 days. Managed to beat it this morning as well, good stuff. So glad I got this for christmas.

I am going through some stuff while I wait for Darksiders and Bayonetta to hit shelfs... Thursday I think? I just booted up the 360 for the first time about 45 minutes ago and I was going to replay some Resident Evil 5 but I was going through my Games Library and I found Braid there which I have not played since I downloaded it. So, so far Braid is #1 most played in 2010 clocking in just over half hour of play. Fucking over rated I think I'll knock it over today and forget about it all over again. Maybe play Shadow Complex again or start up one of my games in my massive back log 2008/2009 back log.

Mount&Blade.  So many hours, so many hours.

10 Man Saturn Bomberman 
   
Check  the music!
  

Metroid Prime 2: Echoes. Finished it last night/this morning. Not nearly as good as the original Prime. Seriously, they could have cut out the entirety of the dark world crap and left the rest of the game as is, and it would have been better.

Left 4 Dead 2

some uncharted 2 is the only game i've played so far this year.
