Ive been without a gaming PC since before 2007. Since then the vast majority of my gaming has been on consoles with some minor PC games my laptop can handle (WoW runs less than 5fp/s i higher end dungeon content for example and I was playing the original Kotor at low settings and bad framerates) so I have played most of the "big" games but the PC has always had its own special breed of games. I have played a lot of the good PC games as console versions, like Battlefield 3 or Left 4 Dead, but that leaves a lot of PC only games I missed.
So I ask you what are the Quintessential PC games to play? What games are so much the better on PC or only exist on PC that I need to play. Ill start the list:
1 - Team Fortress 2
Though there is a console version of this class-based shooter its evolved on PC to be almost a diffrent game. Expanding on the original concept by adding extra modes, weapons and loot drops. The PC version allows for the developers to tweak, upgrade and add to this game at such a ferocious pace, completely for free, that it renders the console versions obselete.
So what would you guys say are the essential PC titles?
