Not at Chimera, but I have played a few:
- The Black Heart Of Camelot
As well as a few others I can't remember the names of (a Robin Hood one, one about Germs, and one where um... I can't explain without spoilers, but let's just say people died, everyone had a secret, and I was in the first offical game)
I RP semi-regularly, and my friends and I used to LARP before we even knew that was a thing (playing pretend) but other than that, my experience is pretty limited, and my LARP-making experience is zilch. (Being a writer helps, however)
And yes, then that is what I'm making. Including the NPC/GM character (because so far, I can't seem to find a way to fit them in without making it boring for the LARPer) I have about 15-16 characters all up. (I didn't want to make it too difficult or big on my first try) there's pretty much 2 groups, but two of characters (NPC included) fit in neither group fully (it makes sense when you see why)
Currently, I'm trying to work out character sheets (so far, so good) but I'm more used to working on character sheets for my OCs I write for, so I'm not exactly sure what I need. As for relationships, I have a few sorted out, but not everyone has a relationship with another character yet... Well aside from the two leaders.
