I like answering this question with specifics!
Bluebeard’s Bride? Two Big Bad Cons ago, run by Whitney Beltrán. Great game and great post-game discussion.
The Warren? I think three Big Bad Cons ago. A two-hour games on demand run by Jason Morningstar and playing with Josh Roby and others who I can’t remember sadly. The tight move set, characterization, and stark horror drew me in.
Mutant Year Zero? Some rando who writes the only APs I bother to read. I should just pony up some redonx ebay money and get a copy…
Lincoln Green? Epidiah Ravachol laying hints on his G+ feed and then going nuts with #Greenwoodwednesday I’m so excited for this game, I almost bought a used Rolemaster Robin Hood campaign book. I probably still will, as it’s got a gorgeous cover.
Gloomhaven? Sophie Lagace and Edmund Metheny have been playing and posting about it. YEAH, I’M CALLING IT A RPG! Who cares, it looks dope. I wish I heard about it back when it was in print.
Action Movie World? Richard Rogers interviewing Ian Williams on Plus One Forward. I don’t think many PbtA games do much that is new, mechanically, and that’s fine and even better when it comes to playability, but this one has a cool meta mechanic which I hated at first and now I love.
I could go on…
