: But it's undeniable that Halo 4 Grifball is the most purposefully put
: together version of the game. Halo 3 was built by Bungie without including
: Grifball at all (obviously, since Grifball wasn't invented until December
: 2007). Reach's Grifball was just Assault with the announcer saying
: "Grifball",

I don't see why giving it's own gametype slot (like Slayer, CTF, etc. have) is that much more significant.

: and it included many glitches in the settings. The "barrel roll" move in Grifball Dash
: was one such glitch, although it was accepted by the community as a legitimate move
: (it was our BXR).

What "barrel roll" move?

: Halo 4 Grifball was the only one that was built from the ground-up as its own
: gametype.

I really disagree, like I indicated above, I think they failed to make Assault fully work and salvaged the parts required for Grifball.

: They brought in Grifball community members to help create the
: gametype and demo it at PAX. They added passing to make it quicker and
: more sporty. They added auto-catch and continuous rounds to make the game
: faster, while keeping options to turn those things off if the community
: wanted. It was clearly given some level of priority during development,
: which Grifball had never received before and many other gametypes (Racing,
: Assault, etc) never received for Halo 4.

I seem to remember Bungie getting input from Grifball community people when they were finishing Reach.
