So after being kicked out of the LARP I played at for like three years, I'm writing a magipunk LARP of my own.
So far there are mechas, catgirls, elves that are a mix of French and Roman Empire snootiness, a nation that's a mix of Brazil and Russia, and the equivalent of Imperialist England on steroids.
One of the rules is actually that the fuel for it is Rule of Cool.
