Left 4 Dead 2 (OMG, this is the game I played the most in my gaming career. 360h since release in November 2009, might not be much to other nerds but still a lot to me)
Arma 2 CO on PVP server (DAO)

R6 Vegas 2 (XBOX 360) in Split Screen Coop with a friend

No CLOD at all

S!

World Of Tanks mainly. EVE Online but now just skilling until autumn hits with crap weather so I have more time to be there in the fleets. Various titles here and there like RoF, A-10C etc.

Exellent..im a Nerd then

Ive clocked up 265 hours on Clod since it was released according to Steam

in the past 6 weeks -
world of tanks
mass effect
IL-2 1946

in order of time played

World of Tanks
Conan Unchained
Theatre of War2:Africa
IL-2 1946 w/UP3.0
RoF
Fallout3
Champions Online:Free for All
Men of War:Assault Squad
and Steam tells me around 6hrs of CloD, but that was all tweaking.

150hrs here... and many more to come :D

Anyone planning on buying Rage? (New game by id Software.) I should have added it to my list.
It looks like it's going to rock.

BoB Wings of Victory from A2A - when I really want to experience the extent of the BoB air battles

Il2 1946 from 1C - still the biggest aircraft selection ever

Rise of Flight from 777 - love the WW1 aircraft graphics and effects there

Combat Mission: Battle for Normandy from Battlefront - best small unit ww2 wargame in my opinion

I hope one day I can include CoD into the list of my played games ...

Team Fortress 2 --> FREE on Steam
Fallout New Vegas
IL2 1946
Pirates Vikings and Knights also free

Guys, sorry to be a little off-topic: do you think that a PS3 is worth just for the exclusive games (and i don't have a bluray player)? MGS4, uncharted, Little Big Planet (looks awesome), etc? If i buy it will share the same LCD as the PC.

Thanks!
