Pluvius writes: "The constantly growing list of games available on Valve's online-gaming network Steam has become even more impressive with a contribution from id software. With the exception of the relatively new Quake IV and a few early games, every PC game released by id is now available, including the first five Commander Keen episodes, the Wolfenstein games, the Doom series, most of the Quake series, Heretic and HeXen, and all of the addons and expansions thereof. Better yet, all of these games can be bought together at the low price of $70, minus a 10% discount if you buy before August 10. Other packages are also available."
