I have games from Steam and GOG (Good old Games) too! It makes it easy to order games and they manage them. No CDs! One of the things I like about Steam there are games from small gaming companies that I play that I know would never make to the game store's because they only have the most popular games from the biggest gaming companies. My biggest fear in the future Steam will do away with the one time purchase of a games and make me rent the games, each month I have to a pay a fee.
