iirc there was a Chess NIP that could be used to implement Go or other games over nostr. Hope someone builds it.

it’s too bad ogs is agpl licensed (no changing) I’m sure there is an open sourced go that could be turned into a nostr client, same with jstris. But, if I spend time on building for games it would be a Minecraft server with nostr as chat and a zap based economy.
