Technical Barriers
: The game's engine and netcode are considered highly unstable by the community even at two players. Adding more players would likely cause severe desync, crashes, and save file corruption.
- Client-Server Mod: one player hosts an authoritative server (dedicated or peer-host) while clients sync. Involves server-side ownership of inventories, crafting recipes, and world persistence.
- Peer-to-Peer with Locking: simple for small groups but fragile—requires conflict resolution (who edits the same chest/building) and reliable state consistency.
