alright as a standard for some turn based or slow trading game neither very efficient nor suited for realtime
only in itself, it can be “temporarily solved” using an extension (like what Forgejo has for relations to Git, e.g. commits) for realtime, it could be something like how godot implements P2P multiplayer (over ICE/TURN/STUN) for federation between servers
Im talking about 3D here (ik about the first lemmy link talking about slow games)
