A write-up of the first two episodes of a Monsterhearts campaign that I’m currently playing in.
It’s a relatively long read and isn’t really descriptive of mechanics (although if you look hard enough, you might be able to guess what was going on, play-wise)–but hopefully it gives a an idea of one type of story that Monsterhearts can tell.
