While I don't agree on the first part, I wouldn't mind the second part from time to time. Halo Fanboys are some of the worst out there, mostly because they tend to fall into the class of "Bro Gamer." (For a reference to what a Bro Gamer is please go Here)but halo haters are crazy anti-fanboys who believe master chief has single handedly destroyed the entire gaming industry and that all the fans of the series should be burned on a stake like the fictinal witch hunts.
Halo: Combat Evolved showed us what a FPS could be, it didn't "break" the mold, just kinda filled it in all the way. Halo 2 and beyond turned into a money grab that gave us the bastard child Halo 3: ODST.I am neither personally, I enjoyed the series for what they are, good thought out games that may not of broken any molds but were solid enough to provide replayability in an interesting universe with mistakes, but few enough to keep you interested.
