Well, Quantum Rage is just too damn short. This is the main reason it didn't get a higher rating. And besides, most Quakers deathmatch with the music switched off anyway. In single player it works a bit better, especially for Quake II where it adds a lot more atmosphere than Sonic Mayhem while maintaining the heavy metal feel. But to be honest none of that really matters, because it's a damn fine album and I listen to it even when I'm not Quaking.
