I hate this. I hate these threads. I hate all the people coming into this thread and simply posting "What do you mean becoming?", under some impression that if they phrase their point in a snide enough way it might be validated.
Well screw all of you. Recently I went back and replayed some sections of the Halo 3 campaign, and I had a blast. No other FPS I've ever played has come close to replicating the same mix of power and vulnerability, small scale shoot-outs and large scale set pieces, and a story which may be generic but it sure as hell memorable. Driving across the collapsing surface of a Halo, kicking down the barracks door and hosing down the brutes with dual SMG fire, blowing up a Scarab (or two), these moments are what make me stick where I am now. Yes, Halo as a series may look generic if you dissect and look at the individual pieces, commenting on where each piece comes from in turn, but it sure doesn't feel generic. But I guess that's something lost on smug gits everywhere.
Also, what is wrong with all the people saying "Halo didn't revolutionise FPS's, that was Doom/Unreal Tournament/Quake etc.". Why do you think only one game can revolutionise something? Apparently one game claims the rights to be 'revolutionary' and then nothing following it can claim that same revolutionary position.
