The first game I designed was a larp for Golden Cobra 2015 (As We Know It). I did some parlor/one shot larps with a local group before it became unsafe. Since then I've hard a hard time reengaging with playing, though I haven't stopped thinking about design.
I think the ideal-world thing I'd like to see with larps (and gaming in general TBH) is people no longer having community/scene growth as a priority/measure of success. Not sure if there's a way to escape that drive within capitalism, but I'd love to see people thinking about how to share successful structures to be implemented by many communities rather than pushing one community to grow beyond the bounds of plausible safety and support.
