I've often found when I'm faced with combat in DW, I'm a little scared. It's hard to judge how hard the threats are going to be and I'm never sure if a particular combat could be our last... and it's awesome. As a player, I probably run from more fights than I've won - not because I'm particularly hurt, but because the tension is so high, I can't see my character sticking around. This is something I don't get from other systems that I've played. Even as DM, I'm sometimes frightened for the PCs like that guy in the movie theater that's shouting out, "No, no, don't go into that room!" I love it. It really makes the game engaging.
So I was curious if anyone has written and/or played in any horror-themed DW adventures? Certainly, most adventures will have some horror elements in it. I was wondering if anyone has gone full-horror on a game or two, what it looked like, and how great the tension was.
