After playing around the in multiplayer space I think it might be nice to add Share options between players. While it’s fun to build with a friend or in tandem from different locations a lot of the meta game is locked down during co-op.
You cannot play as specialists very easily because you need to manually trade EVERYTHING. This makes sharing any kind of consumable item tedious to impossible. This issue could be erased by implementing a shared stash system (allow all owned objects to be usable by any player’s hearthling). Either a server with sharing option or an in game bilateral choice would be a plus.
Once a share system is implemented the meta could be described as multiple factions who are building a community together. Each faction leader can only control of their own faction’s people. Each faction can then share and build together or try to create competing communities.
