Someone definitely proposed a NIP for high scores and had plans to expand the NIP. Damned if I can remember who it was now though.

No but we could @c4f5e7a7…8856cac7 has a version I can’t remember the details, my only issue with it was there had to be a game server to sign the score. Everything I built was static site and user signed so it didn’t really work for me (although I guess I could build a work around)
