Doom had a much greater impact on the gaming industry, as it actually innovated and had a powerful sense of style and atmosphere.
Look I never said the game was horribly crap, merely that it was average to above average. The anti-libertarian/anti-objectivist message underlying the game is really starting to annoy. That might be the main reason I have such a negative gut reaction to this game. It tries to push a shallow greenpeace-like anti-philosophy that is against scientific investigation and self-improvement of the human species. The kind of gene manipulation so derided in this game is really the only hope we can have for the future.
