Concept: “The dumbest sportsball game you can play!”
Content: Watch teams of five scvm wail away at each other. A ball is also involved.
Writing: A clean and functional ruleset for a chaotic death sport.
Art/design: Heavily stylized design elements and effective use of sparse illustration make for an engaging but functional rulebook.
Usability: Easy to reference, quick to play. You (probably) won't lose your head.
