@eladrin my list of stuff I'd like to GM consists of different settings I've got scetched out in my head rather than specific systems.

A gonzo planescape-inspired city thing where basically anything goes, a dark souls inspired realm where memories are a tangible thing and even the land is forgetting itself, Roadside Picnic inspired small zone I've lightly mapped out with it's own anomalies and monsters, World that operates entirely on videogame logic etc etc.
