Cabal Online
Nooooo I'm so jealous!

That is officially the coolest looking mmorpg I have ever seen in my life. Sucks that you can't play it in America. I think there's a way but it's way too complicated...
I could never recall all the games I have ever played for the PC so I'll just name the games I actually played a decent amount of.
Oblivion
Diablo II: Lord of Destruction
F.E.A.R.
F.E.A.R. Extraction Point
Halo
Condemned: Criminal Origins
The Sims with every expansion
The Sim 2 with almost every expansion
The Sims Online
Silent Hill 2, 3, and 4 (since 1 was for Playstation)
Doom 3
Doom 3: Resurrection of Evil
The Sacred Rings
Unreal Tournament
Serious Sam
Civilization 4 (Well I barely played this one, but I figured I'd add it anyway)
Tales of Pirates
Midmarch
Guild Wars
Silkroad
Sim City 2000, 3000, and 4 deluxe edition
Nibiru
Scratches (VERY scary. Must play is you LOVE serious suspense

)
And Then There Were None (Yea the game based off the book. Not a bad game.)
Barrow Hill
Zoo Tycoon
Ultimate Ride
Still Life
And that's all I can think of right now.
