Oddly enough, 343 has given Grifball even more love than Bungie. It's a gametype entirely created and maintained by the community, but 343 gave it a huge leg up by including it as a real gametype in Halo 4. We were incredibly lucky -- gametypes that were hard-coded into Reach were dropped, but Grifball, which was not hard-coded in Halo 3 and only half there in Reach, made the jump.

No racing. No juggernaut. No assault. But Grifball is in Halo 4, better than ever.

We're not sure why they chose Grifball, but it gives 343 a heck of a lot of goodwill from the Grifball community, since we know we might have faced the same fate as those other lost gametypes.
