Cyberpunk is apparently of more interest than fantasy in a 60:40 ratio amongst indie gamers according to a poll I happened to run recently with 40ish responses.
I think there are lots of reasons! Fantasy is seen as having been ‘done’, both by trad games and DW as a sort of all-encompasding capture of the experience. Cyberpunk fits the current world mood. Diversity fits more naturally into a ‘classic’ picture of cyberpunk than fantasy. Fantasy in our heads is a genre of adventurous epics rather than tight-knit emotional stories. And probably loads more.
