I mean whales, the original dev for Cataclysm intended the sequel to be based on an island, this as I’ve said before would make it easier for the world to have more of a story, simulate NPC actions, perhaps NPC squads gathering resources for settlements, and fun politics, territory wars, things that would make this game feel complete to me.
With a limited scope, less CPU cycles would be necessary, and you could choose an island size on worldgen that’s smaller on weaker machines.
He intended for this sort of thing to happen before his real life became too important.
