Games I have conquered!
This is a list of all the games I have ever beaten from start to finish without cheating. I've included racing games for which I have unlocked all tracks and vehicles. For multiplayer games like L4D, I include them if I have beaten all campaigns or unlocked all areas. I am not including games that don't really have a measurable total amount of progress such as Counterstrike: Source or Team Fortress 2.
I'll be adding more as I either beat more or remember more. There's quite a few years of gaming to be enumerated here :)
