I will be running Monsterhearts. A powered by the Apocalypse game of teenaged monsters. It's not really for the faint of heart and I encourage you to bring as much teenage melodrama and self absorption as you can manage. The story doesn't matter nearly so much as how you feel.
You play monsters in a modern setting. Monsterhearts is part of the increasingly popular lineup of Apocalypse World hacks and focuses around the intertwined lives of a group of monsters struggling with their lives as teenager.
There are usually many moments of humour in the game but it's usually raging hormones, anger and the struggle to fit in that drive these stories.
