Multiplayer is a big topic and it is obviously on our minds. The big questions is what type of multiplayer would be the best for this kind of game?

Would it be coop where each player would start on their corner of the map? Or would it be shared factory? Of maybe each player with its own island + trading?

Also, it is technically very challenging, since the entire simulation must be perfectly deterministic. We actually have most of the things deterministic, maybe like 95%, fixing the last 5% is a lot of work.
