Yeah, I'm running it as a side campaign to my more heroic one. I do pretty well when I run horror games, if I do say so myself, but spending a year or more (elongated due to pbp) with my face in that sort of grimness would be a lot for me otherwise.In the end, the party doesn’t even end the large evil, they just prevent a possibly worse evil from happening. This, combined with the grimdark tone, could be a major turnoff to a lot of players who prefer to feel more heroic.
