I've played several sessions of Monsterhearts and love it.
You might be tempted to dismiss it as a Twilight pastiche but you'd be missing out - it's way darker and serious than Twilight - or at least it was whenever I've played it. For me, the TV show it comes closest to is Being Human. But a neat thing about it is depending on the character classes the players pick, you're going to get a different show. If somebody picks the Mortal - sure, it could end up a bit like Twilight or Vampire Diaries. (It could also end up like Let The Right One In.) But if you have Ghost, Werewolf, and Vampire? Being Human. Have a Chosen in there? Buffy. Or, most likely, a weird combination that's something completely new.
You might notice that there's sex in it and maybe you think that's a little creepy, but you'd be missing out. Hey, you don't have to engage with the sex rules if you don't want. Or you can keep it all PG rated: "We go in the other room and do it." No need to go this far (in fact, please don't if I'm playing with you.) And hey - it fits the genre. There's sex in Buffy and True Blood and Vampire Diaries and Being Human.
In the games I've played and run of Monsterhearts, innocents and not-so-innocents were seduced, names were called, hearts were broken, bullies were killed and returned from the dead (with demonic baggage), a ghost took a day trip to the earth's mantle so he could melt an amulet forged by Hephaestos, a church was blown up, demons were slain, policemen were addicted to experimental drugs, and a witch got her visions from a memory house - but her mother was in every room.
This is what Vampire: The Masquearde and all those World of Darkness games should have been.
So preorder it. Because I signed up for the "Joe runs two sessions for me" perk and want to collect.
