We did French Revolution where the Revolution didn’t happen because Louis made a deal with Baphomet.
It was 10 years later in a demonic post apocalypse Paris that was basically a demonic playground with the PCs trying to protect their neighborhoods while figuring out if revolution was still viable, or if they would rather sell out for security.
The game required very little hacking. Really, it’s an early modern period so you just assume guns take longer to reload and you have cypher books and pigeons instead of cell phones.
Hacking to the premodern era is way harder as urban power dynamics were very different.
Anyway, Finland is awesome. And in PtbA games when I MC and a player misses I basically do whatever I want that fits the agenda and directive of the game. Including totally giving players awesome shit that they didn’t expect they’d ever get.
Like some girl going into a basement, blowing her Keep Your Cool roll and ending up with some famous dude’s lightsabre. Certainly nothing interesting could come from that.
