I'm holding out for Crab Champions, all these other crab fight games coming out are just trying to cash in on the hype (although my understanding is at least FightCrab was in planning before Crab Rave came about, so it's more coincidental than anything, so no stabs aimed at them). I mean, I don't know if Crab Champions is gonna be great or anything, but it's the official game spawned by the Crab Rave music. And my partner and our friends all love us a good Crab Rave.
EDIT: I wonder if the game will be faster than it appears in that video, because it seemed really slow motion. But it looks funny as hell.
