Well, it's not up to me whether it's useable or not. The game would have to be set in 2063, and the GM would have to approve the concept.
Year of the Comet is a sourcebook about the year 2063, where Haley's Comet comes around and all sorts of weirdness happens (either because of it or alongside it). One such thing is SURGE (Sudden Unexplained Recessive Genetic Expression) which, from a metagame point of view, is basically a way to include some furry and anime tropes in the game. Most of it is (IMHO) junk, but hey, I can't say no to catgirls.
