> Halo (and really, Rare's FPS platform) brought the FPS niche from PC+keyboard+mouse to console and controller. This introduced casual gamers to the world of the hardcore competitive nature of Doom/Quake/Unreal Tournament, a multiplayer environment where winning meant shooting your friend in the face. You didn't have to maintain a massive gaming rig or be committed to computing in order to get into FPS now. All you needed was an xbox.
Quake III was released on the Dreamcast. Duke Nukem 3D was released on the Saturn and Playstation. Doom was released on the Megadrive/Genesis. Halo wasn't the first FPS to be released on the console. Not by a long shot.
I certainly agree that those games appeared earlier on the timeline. But Halo/Rare FPSs were the first to be outstandingly successful in their control and playability scheme. The console versions of those games you list were hampered by their platforms and would all likely be considered less playable than their PC counterparts. Thus the genre could not break in as it could with Goldeneye or Halo.
