NEW YORK (CNN/Money) - Since 2000, developer id Software has told the world the next installment of "Doom," the game that kicked off the action genre, would ship "when it's done." Good news, gamers: It's done. In the lexicon of the industry, "Doom 3" has gone gold.That means with id Software's work done, publisher Activision is duplicating copies to ship to retail. What it all boils down to is you'll be able to pick up a copy at retail on Aug. 5, though some stores could start selling the game as early as Aug. 3.
