i'm so curious to hear if any other GMs have a game that absolutely fascinates them, but they're worried about running for one reason or the other?

for me, it's Bluebeard's Bride, a game i discovered through a project my sister made for her fairytale class. she used images from the rpg to tell the story and i was immediately intrigued! i went on the website to get more information and discovered it's a very intense horror game where the players all play different aspects of the same woman, who's exploring her new husband's house and finding the horrifying remnants of his past wives. it deals with very intense subject matter, specifically abuse toward women, and it seems like a very intense gaming experience. i'd still love to run it, though i'd for sure have to be clear with my players about the trigger/content warnings as well as really stress safety tools.

nevertheless, do you guys have any games you've discovered that for one reason or another you're hesitant to run? it doesn't have to be as intense as Bluebeard, just something about it maybe wouldn't work for your usual group or maybe there's an aspect of it you don't feel you can pull off? i'd love to know!
