Vampire LARP one-shot systems

A request for help with a first Vampire LARP reminded me that, as an observer from a safe distance beyond one-shots, I actually know a bit. Published LARPs, variant systems and the like. Might as well put my links here.

By Night Studios have resources (enough to run a V20-era LARP with a tablet) as well as a quickstart and Storyteller advice.

Published adventures, not many but mostly available on DriveThruRPG

Some free unofficial ones, among other genres

The really really system as used in End Of The Line and Enlightenment In Blood, nice and simple.
