Adventure by White Wolf (almost a decade old now)
Daredevils... hmm... early 80s
Hollow Earth... 2006? uses Kickstarter a lot to built their line of books
Justice Inc - hero games, been around for awhile.
Spirit of the Century... FATE, been around for half a decade at least
Deadlands Noir? Pulpish I guess.
... others?
Anyway, not sure its a new craze per se. Are there any other newish ones?
