This is awesome. Valve has arguably the most loyal fanbase in gaming, and this is why - they do good by their customers. Sure, they may lose out a little by not making profits on DLC, but they can pretty safely bet that the next game they put out will do well, and the one after that, and the one after that, just because they have consistently pleased their fans. I have heard that when Half Life 3 comes out, preorders will involve filling out a questionaire asking, among other things, what your favourite type of alcohol is, what your sexual preference is, and when would be the best time for the incredibly attractive, intelligent and funny person of the appropriate gender to visit your house with a case of the aforementioned alcohol, install the game for you, then spend the next 24 hours at your home doing whatever you want. I think it's legit.
