While I've yet to get A NOCTURNE to my table, I've spent the past five years running a variety of other Forged in the Dark games, and I think this one stands head-and-shoulders above all the others except Songs for the Dusk. I think it avoids a lot of common pitfalls (cleaving too closely to Blades, having thin re-skins of that game's playbooks, etc), and all of the wholly-original stuff here is confident, compelling, and unique. I know several other designers who cite it as an inspiration for their own FitD work!
