What game should I gett

I haven't played a PC game in like 5 years so I was wondering if there was anything you guys recommended that I may have missed. Not crysis or wow or anything that's on the xbox too.

Thanks

Just because I know I won't be able to play it on my computer. And no wow cause that's the 1 game I did play but it was the demo.

Thanks thusaha and danieldust and any others that people have would be great.

Allright then

Team Fortress 2

Half Life 2

Far Cry

Doom 3

F.E.A.R. (i think its pretty linear + repetitive but many other ppl think otherwise)

Half Life 2 Episode One + Two

Rainbow Six 3 Raven Shield

Dawn of War

Company of Heroes

Oblivion

STALKER

Rome Total War

Battlefield 2

I listed pretty much everything I could think of....you need to give us some specifics so I can narrow the list down

Audiosurf (only $10. get from steam. best PC game of 2008 IMO)
The Orange Box
STALKER
Oblivion
Morrowind: Game of the Year edition
FEAR (one of the best SP shooters I've ever played)
Counter Strike: Source
Battlefield 2: Deluxe Edition
Battlefield 2142

If you're unsure about how they'll run on your computer, do a test here

-F.E.A.R. Platinum Collection (3 games for $30)

-Dawn of War Platinum Collection (Again, 3 games for $30)

-Unreal Tournament (Not everyone likes this, but I've logged quite a few hours in it)

If you're looking for a free game or MMORPG, I highly recommend Dungeon Runners. If you don't mind paying, you can get membership for 6 months, all for the cheap price of $20.
