Wow I have so many games on my PC and have had so many which I deleted to free up HDD space... Gears of War, Halo 1 & 2, TESV: Skyrim, Mass Effect 2&3, Borderlands, and I could go on, I'm not even sure how many PC games I have lying around. I wouldn't say I play them often but I do play them for long sessions. Titles such as Fallout New Vegas, or Skyrim I could play them for hours on end because there's so much to do, and so much to see.
