Introducing a vertical circular bus - A giant O of belts and lifters fully connected allowing for input / output anywhere along the bus.
Pros :
Modular, you can build anywhere on the vertical bus stack
Limits spaghetti by providing a clear and easy to access API for all players.
Very fast to reach all parts of the factory since everything is very concentrated into a cube of productivity.
Cons :
Satisfactory netcode doesn't like SUPER dense areas, so it could become problematic for multiplayer.
There is no priority mergers yet in Satisfactory, so if you want to prioritize a input to the bus you downgrade the belts/lifters feeding INTO the priority input, that way the belt will back up and the priority input will provide the bulk of the material.
This is what I would dream of making if my computer's performance was any better. I'm amazed.
Sadly with significant lag incurred the last time I tried to make a mall even half this size, I ended up switching over to a distributed storage model kept at factories dotted around the map and tapped remotely via drones.
What Jet said, if it was over a year or more ago you should give it another shot. The optimizations they made around loading and lag has been a night and day difference. Same with multiplayer lag.
