My preferred RPGs for Holloween avoid the hell out of the holiday.A few years ago, I ran a deeply mediocre Christmas adventure and then, last year, an even bigger wet fart of a special adventure. However, I made a great town the first year and it occurred to me that what I probably ought to do is return to that setting each year and just add extra holiday adventure stuff onto it.
But this is spooky season. If one was making a Halloween setting, what would you put in it? Assume you'd want a (relatively) safe village for the player characters to work out of as a home base, but what other stuff would you add to such a setting? It doesn't need to be as robust or "realistic" as a regular D&D setting, since this would be mostly used for Halloween-specific adventures and include those tropes.
I ran the first Carrion Crown adventure, and my players got crushed by the haunts. They didnt know what to do. Instead of trying to figure the encounter out they just whined, cried and gave up.Lot of good ideas to take from Paizo's Carrion Crown. Namely haunts and spirit planchettes, so much good flavor.
