Thats your opinion, not a fact. In fact I believe ID has released some of the worst games ever, mostly from the perspective of failing to live up to the potential. The main one being Quake 1.
maybe Quake1 single player wasnt the greatest, but take a look at multiplayer. Quakeworld. enough said.
Wolfenstein and doom were inovative yes..
Yes slightly innovative. probably the sole reason why the FPS is around today.
ID.... bring it on... bring it, the fuck on... lay these retards to rest.
