Hmmm I have quite a few PC games actually. I'm a huge fan of the Total War series. If you are a fan of strategy I highly recommend them. The Witcher is a great Adventure/RPG once you get the controls down, and the Civilization series is great as well.
Civilization - probably the best turn based strategy I've played Rise of Nations/Rise of Legends - great real-time strategies Unreal Tournament - best series of shooters ever Call of Duty 1 - the best in the franchise Serious Sam - killing mutants in a strange Egyptian place Homeworld 2 - another fun strategy Halo: Combat Evolved - best in the Halo series Trackmania Nations - great racing game with a nice map editor
They're games that come to my head instantly but there are hundreds of good games for the PC.
definitly has to be the diablo games. not the first one because that on suckd, but the 2nd one, the expansion(lod), and the third one were completely awsome beyond all comprehension.
Um, I haven't played that many PC games, so I'd have to say WarCraft 3. If MMOs count, then Runescape. If games that I played on a different system that are also available for the PC count, then Halo: CE and MW2. Oh, and a lot of games on here by Krin, John, and several other authors. Sonny, Colony, Exit Path, The Only Level/Too, Upgrade complete, bubble tanks, :the game:, Age of War...
diablo because its fun and mostly the only thing that will run on my pc because everything else is to powerful and i dont got money to upgrade everything
