Alright, I'll bite. What FPS('s) before did you quickly regenerate all your health if you can go a few seconds without getting shot? I'm not trying to be snarky, I'm genuinely curious; I'm a pretty seasoned FPS vet, and as far as I know, Halo was the first game to use this kind of system, which has since become the standard for first-person shooters.
There were a few other big things that set Halo apart from the pack. Split-screen co-op is one. While it's not exactly original, I can't think of any good FPS's before Halo that had decent splitscreen co-op. (Perfect Dark tried, but the framerate was pretty terrible.)
Seamless vehicle integration was another. While certainly not the first game to incorporate vehicles, few games at the time had vehicles that were as much fun to drive as Halo's warthog, banshee and scorpion tank, and that you could jump into and out of at any time.
