Duke Nukem 3D is my favourite FPS. And I've played so many FPSes, from Wolfenstein 3D, to Blake Stone, Operation Body Count, Corridor 7, from Quake, SiN, Doom, Strife, Heretic all the way up to Half Life 2, Doom 3 (which I also loved, but liked Duke3D a LOT more still), Far Cry and so on.
Yet when I went back to play Duke3D, I couldn't stop playing it, even though I played it like 10 times through already. I don't know why, but I guess it's just a great game. And it's not the first FPS I've ever played either, so it can't be "because you were a kid and your mind was more malleable".
So, what about you guys? I would definitely rank Duke3D as the best FPS of all time. And if 3DR is trying to top Duke3D with DNF, I say take their time.

Wrong forum but... Deus Ex (NOT invisible war) is the greatest FPS ever made, if not the greatest game ever made.
I don't really have a second place, they all pale in comparison as far as I'm concerned.
