Oh so many LARP ideas! It hasn't helped that I've been researching them and therefore seeing everyone else's juicy, juicy LARPs. Cthulhu-based occult mysteries? Yes, please! Trail-esque skill point spends? Why not?! How about fantasy romps through myriad modules? Mm, yummy! Zombie bash ups? How is this not a thing already? Mainstream murder mysteries? Should be plenty of these out there. Covenant-style vampire games (each covenant has their own sessions)? Already written up a booklet per covenant!
I think the hardest part about running LARPs will be limiting myself to only running certain LARPs.
