I always have a long-term campaign running, but on nights when we don’t have a full complement I open up our weekly game night to all comers and run RPG one-shots (or pull out some board games when I need a break). I’m looking for recommendations to expand my repertoire—specifically, RPGs with quick set up and tight rules. I’m trying to build a set of 7-10 games of varied genres that I can always have on hand, ready to go at a moment’s notice.
Our most-played one-shot is Fiasco, which I have run many, many times. I love it, but I also enjoy mixing things up mechanically. I’ve also run Psi-Run a fair amount.
Other one-shots we’ve tried that hit the trifecta of a low-prep+tight rules+satisfaction within a 2-4 hour time frame:
- Soth
 - Lovecraftesque
 - The King Machine
 - Carolina Death Crawl
 - Bootleggers
 - Fall of Magic
 - Durance
 - Dread
 
One-shots we’ve tried that hit one or two of those marks, but not all three:
- Battle Between the Worlds
 - Spirit of '77
 - In a Wicked Age
 - The Quiet Year
 - Cheat Your Own Adventure
 - Ghost Lines
 - Microscope
 - Into the Odd
 - Tales from the Loop
 - Night Witches
 - The Warren
 - Funnel World
 - Freebooters on the Frontier
 
Please share what’s in your portmanteau!
      
    
  Perhaps they are classics, as I can remember them?
