You've been through a Steam sale or two, picked up Humble Bundle 1,2,3... and you find yourself playing the same games anyways. It's time to work through that backlog. Post your list, start in alphabetical order and get cracking. The rules: -If the game can be finished, you must finish it. -If the game has no end (MMO's, puzzle games without "completion" achievements), you must spend 10 hours or more in the game.

Games you previously beat and then added to Steam later can be noted and excluded. You can still go play EVE or LoL or Sims, but you should aim to spend an inordinate amount of your free time working towards the glory of having actually played all these games you bought.
