PC GAMES ONLY!

[imperialreign]

Thief series - 12 years old now, but worth getting to run!
STALKER series
FEAR series
Metro2033 - worth playing for the atmosphere and story
Descent series - bad-ass with two joysticks!

awesome, but overlooked RTSes:
Dungeon Keeper 1, 2
Populous: The Beginning
Black & White 1, 2
Homeworld 1, 2
Dark Reign 1, 2

Hitman: Codename 47
Crusader: No Remorse; No Regret
Jagged Alliance 1, 2
Tribes
Mechwarrior 4

Baldur's Gate
Icewind Dale

Damn, I could probably keep going

Good suggestions so far and many of mine have been taken.
Sooooo...
Jagged Alliance 2, don't worry about picking up a sequel you won't miss much.
and
The Operative: No One Lives Forever and No One Lives Forever 2: A Spy in H.A.R.Ms Way. The game that six months after Half-Life release out Half-Lifed Half-Life. Funny and smart with engaging characters and a goofy sixties spy story. Bugger if I know where you would find them though. I guess you could try an online auction site?

Half-Life 2.
The Unreal Tournament series.
Drawn: The Painted Tower (Probably my favourite Point'n'Clicker )
Saira (Neat platformer. The graphics <33)
Zeno Clash (really awesome Brawler game)
Amnesia: The Dark Descent
Defence Grid: The awakening (TD game)
The Elder Scrolls series
Torchlight

That should cover things nicely.

Team Fortress 2, Mount & Blade: Warband and Battlefield 2 are all fantastically designed time-consuming games. As a bonus, even if your PC isn't that powerful, you can still run all of them with ease.

Go to GoG.com and buy Baldur's Gate 1+2, Planescape: Torment, Icewind Dale 1+2, and Neverwinter Nights.

All are about $10, and optimized for current operating systems.

Not fair, those were going to be mine....cept for planescape, never played that one. Really though, ive yet to play an RPG that treated me as well as Neverwinter, and I've played a lot of modern ones.

Oh, i guess Minecraft too, but.....Neverwinter.

[Digitaldreamer7]

BattleField 2 - Still a great massive player FPS
Planetside - Kind of the same deal as BF2 but futureistic (Or you could just get Battlefiled 2142 but the community is lacking for that one.)
Any of the MMOs a good for killing time. (If thats your thing)
Minecraft (It is that good)
Diablo 2
Dungeon Keeper
Galactic Civ

Hop on Steam and buy a few games from the under 5$ listing. (Might suck but always a chance of being great.)

planetside a million times (man I gotta resubscribe just in case the 5-6 year loyalty will carry over to planetside next)
and of course, MUDs I do love me some MUDs, and most of the catalog on Gog.com

OMFG planetside. The best FPS ever (IMO)

 

[jawakiller]

Minecraft, Counter-strike, TF2, Mount and Blade, Beat Hazard and Half-life 2. Just to name a few.

Tis true! It remains one of the best 3rd person games of all time, IMO. It's a bit old now, but still worth a look, I reckon!
