I ran this with my Blades in the Dark group last weekend and everyone seemed to enjoy it! My favorite part of the game was when my players leaned into the provided player characters' backstories, personality, and occupations – despite being minimal, they're well designed so it created a lot of amusing interactions – and I loved how the Hysterias only emphasized this further.
As a first time GM five sessions into our Blades in the Dark campaign, it was a little jarring that the Night of the Hogmen encounters are provided linearly but I ran it that way and my players didn't seem to mind.
If I were to run it again, I'd make a few changes to how I presented the game. Our session didn't feel dangerous enough – I think I started most social encounters in "controlled" because the NPCs had no reason to escalate but I think it created tame encounters – I think I'd go with "risky" next time. I'd also make the danger feel more urgent – there was indecision that felt out-of-place in the setting. I'd also be more explicit that they needed to prepare for a siege – it wasn't apparent until a few encounters in when they saw the clock ticking. And finally, I didn't realize it when prepping but a few encounters fall into common horror tropes and my players were quick to realize and avoid the consequences. If I were to run it again, I'd try to be less obvious. That being said, even without this, we had a good time.
Thank you for putting this together at a name your own price – I enjoyed it and I'm looking forward to future releases!
