One of the nice things about recording all our online game sessions is it makes it pretty easy to simply look this kind of thing up. (I knew the answer, though I was curious about the specific numbers.)
The 'winner' in this case is a apocalypse engine hack I built for our Star Wars game (a campaign that went through three rules systems over the course of 30+ sessions). My hack (here: https://www.dropbox.com/s/fwnq7ok585thk1c/SWW%20Rebel%20Ops.pdf?dl=0) is a rebel-era adaptation of Star Wars World, which in turn owes DNA to Urban Shadows, I think (understandable, since SWW was written by Andrew Medeiros). Since August, I ran the game eighteen times. That game wrapped up at the end of April.
Aside from that:
– Ran a six-session Dungeon World adaptation of Deathfrost Doom, plus a couple asynchronous DW adventures with Kaylee, via Google+ polls (http://randomaverage.com/index.php/2016/08/dungeon-world-with-kaylee-via-google-polls/), so call that eight sessions.
– Ran a couple sessions of Lady Blackbird (someday I'll run a game that makes it further than escaping the Hand of Sorrow).
– Ran four short sessions of a World of Dungeons: Breakers/The Secret World mashup, just recently.
– Played (actually played) in a couple sessions of DnD 5e (Adventurer's League), and ran a couple sessions for my family. Solid game.
– Played (actually played) in a Dungeon Crawl Classic 0-level "funnel" game. (You can't spell funnel without FUN.)
– Ran at least one or two games of No Thank You, Evil! with the kids.
So: That's ~36 game sessions since last August, with 50% going to the Star Wars Rebel Ops pbta-hack. Not too shabby, really.
