Well not matter what the Pc "Elites" thing (...) ...
Halo is definitely one the first and most successful attempt to port the FPS genre to the console world. Judging by the big popularity of the genre on the console world now, I belive it was worth it...
Now to ask if it is responsible for enabeling many good games is the wrong question.
Is Wolfenstein 3D responsible for bringing many good FPS game on the PC ? Of course, but there is also a lot of very bad games as well...
Note : Halo Wars is trying to do the same with the RTS genre... and technically it does quite well.. 
(you can believe me, I'm an ex PC fanatic).
Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.
