Looking for fun, low req. pc games?

Thats a really nice selection there already, loved all of those. If you haven't already give World of Goo or Braid a run, very much worth it and it's right up your alley. Other than that, Torchlight, Super Meat Boy, Gemini Rue, Amnesia, Planescape Torment, Half Life 1 & 2, and especially Portal would all be winners.
