I haven't told you, I played #Masks (a super hero #RPG with a #PbtA engine) last satursday and monday, for our season 2. It was just as awesome as the previous one, I can't recommand this game enough. Characters are fluid, they will evolve sometimes beyond your control, and it's super cool (really, they are growing up and trying to figure who they really are - and it's tough for a teenager). This game is really team focused, so between action scenes there are cool downtime centered on inter PC relationship.
I truly love it, probably one of my favorite RPG yet.
