We use the word “niche” a lot to talk about JRPGs or strategy games, ones with audiences that aren’t exactly everyone. Still, most of these have a widespread following. Superbeat Xonic is niche in the truest sense, though: a release tailored for one specific, small group and virtually no one else. It doesn’t try to broaden its appeal with higher production values, lessened difficulty or modern game mechanics. It invests all its time and effort into one target type of player, and everyone else can just move along.
