Think there could be a nostr based RTS-MMORPG game using this and siloed relays (whitelist read/write). Uses real money in game. permissionless. Would have to be crafty to dream it up.

RTS over relay is not a wise idea
game state is in relays. https://www.loro.dev/ client side. events are time stamped. maybe it wouldn't be real time, but there's some real time things happening on nostr already.
