The problem with Vampire LARPs.
Long time larper here. I've been a member of the Camarilla/minds eye scociety/whatever the fuck you wanna call it for over 20 years now, and I've noticed a pattern.
Vampire larps are prone to a particular kind of toxicity that makes the whole experience turn to shit unless very carefully handled. And in all honesty I've yet to see anyone handle it well enough to prevent any given game from detonating.
The first factor is intensity. All role playing can suffer from character bleed, where the player identifies a little too closely with their character. I posit that LARP as a format is particularly prone to it due to how immediate the whole experience is. Even veteran players will get just a bit to into it. It's inevitable.
The second factor is the main premise of the Vampire venue itself. It's expected that your going to be a bastard. Deception, manipulation, status games and betrayal are baked into the games very foundation. It's not just a option to play, its the default.
Combine these two factors and you get the toxicity that kills so many Vampire games sooner rather than later. Basically: your character is going to get stabbed in the back sooner rather than later, its going to feel very personal when it happens and generally won't result in a positive experience for you.
Looking at the history the the Cam/MES/whatever you can see this dynamic writ large. The club is crippled with dysfunction- cliques, vendettas, grudges and hard feelings. Most of which can be traced back to some in-character moment where someone got screwed over and took it personally.
Thing is, im not sure there's a way around this problem. The toxicity is baked into the premise of the game. Other venues like Mage or Changeling don't seem to have quite the same intensity of the issue, as their foundational premise isnt as antagonistic between players.
So what are we to do? Imho the first step would be to publicly (and loudly) name the damn problem. But after that I don't know.
