But maybe you should have to, if you're going to ask people to plunk down money for something. Same old stuff like "Doom" is why the video gaming industry is stuck in the horrible rut it is. It takes attention (and hype-driven consumer dollars) away from the (very) few cool, interesting new projects that get lost by the wayside.

Ever notice that "gaming industry" is an oxymoron?
