Just a couple of things:
Ex rock band singer right here, and very interested in your LARP idea Mike!
And Tourney? Sounds like an awesome opportunity to throw all sorts of interesting towns folk in there!
Lastly, i completely agree about the Defense of Nurumburg. I think this game has gone completely under the radar as an idea in general and it was an excellent opportunity for noobie players, or just general non combatant players, to learn how to fight and create characters. It pretty much taught people how to combat larp in every aspect of the game, and i really like how they used the whole “more health if together” rule to teach new players that you’re not going to die so easily if you LARP in numbers!
I think a large scale version of the Defense of Nurumburg should be run again, and to be honest Adam and his wife (sorry i didn’t catch your name!) were great GMs, who even taught people larp bow fighting (which ended up being extremely effective in the fight, i got nailed).
I would strongly suggest it, especially at the likes of Chimera where there are so many new players.
