It's also significant because since Quake shipped 18 months ago, we have seen a steady stream of challengers, games that have been trumpeted by press and players alike as the successors to the first-person throne. Considering the countless hours invested by countless players in the game, that's a remarkable achievement. Within moments of starting the game, it is safe to say that all but the most irrationally loyal players will acknowledge that Quake II is better than the original in every respect, and that no one who can afford to upgrade will have any reason to ever load Quake again. Whatever else may be said about Quake II, one thing is certain: It is the only first-person shooter to render the original Quake entirely obsolete.
