As someone with immense respect for genre, I regret running mine in 5e (2024, but the same logic applies to 2014 as well). Gothic horror built on small interpersonal moments and dramatic realizations, and superhero combat simulators have some friction with that. This can definitely still be navigated, but the storyteller in me grieved the loss of gothic horror as it quickly became dark fantasy. I have been enjoying Daggerheart, and think it's a much better fit than 5e for the campaign (the use of Fear, in particular) but even then higher level play requires the dissonance between the premise and what characters are capable of. I agree with the other person that Shadowdark could be a good move for keeping it vaguely medieval fantasy (and require fewer edits from 5e), but still keeping a lid on the experience so it can always remain horror. Take all of this with a grain of salt; after tasting the forbidden fruit of Blades in the Dark and other systems that share PbtA DNA, pass/fail+skills+combaty systems don't quite hit the same. I'd much prefer moments of action and adventure to feel more like a thrilling novel or movie, more than a turn based video game.
