Monsterhearts is a tabletop roleplaying game by Avery Alder (buriedwithoutceremony.com). It's truly excellent, and one of my favorite games. Because I really love it, I made a bunch of content for it, and a lot of my experiments have been good enough to share!
The Doppleganger Skin
The Doppleganger is all about self-loathing, hero worship, and the vicious cycle that those two traits lead to. The Doppleganger can become the very people they idolize, and in doing so discover that they're not a hero: they're just a person like you.
The Ghost Skin (tLBP Version)
The Ghost is one of the official core skins, but it didn't really go about its themes or mechanics in a way I personally found fulfilling, so I redesigned it to suit my needs. This version of the Ghost focuses on how, despite trying to be caring and empathetic, helping people is still a move in the social environment and hierarchy. It uses Conditions in a novel way, and tries to fight the tendency toward passivity and inaction that the original Ghost has difficulty with.
The Witching Hour of New Year's Eve
A Monsterhearts quick-start scenario about a New Year's Eve party hosted by a central character named Darren that all the players have their own complicated relationships with. For 3 or 4 players and an MC.
The Ice Queen Skin
This is a reskinning of Orion Canning's Skin The Firestarter, altered by Rebecca Gold and laid out by me. Where the Firestarter is consumed by their fickle hatreds, the Ice Queen is cold and indifferent in a way that's almost intoxicating.
The Fledgling Skin
A collaboration with Rebecca Gold. We like Vampires, but media has a bunch of depictions of vampires that don't really line up with the official Vampire skin. The Fledgling is a young vampire, not yet in control of the powers they now have or the new urges they're feeling. They deal with the high of power and the lows of need in a different way than the addiction cycles of The Ghoul or The Infernal.
I also have contributed to a lot of Monsterhearts content, either in playtesting or in layout work. Among these are The Firestarter, The Demi-God, The Janus, and The Hoax, most of which are not yet available.
