A while ago, I was working on an idea to run a computer driven game where characters were defined by a string of alphanumeric characters. It got a bit of interest, but I never really took it anywhere.
Actually, digging back through those posts, it's actually where I was thinking of heading.
I've been having a bit of trouble maintaining the motivation to regularly upkeep the LARP in recent months, so it might make things easier to automate the whole thing. To generate characters via a basic website, to track factions based on which characters belong to them, and to map the influence of those factions across the map of the LARP world.
