Last update, Update: 17 Jan, you've removed Silicon Mine, Silicon Refinery, and the Electronics Factory, the whole chain. You should restore this, it's a good chain.
And make these changes.
- A) Remove (or keep it too) steel demand from the Electronics Factory and replace it with (or add) silicon.
- B) Add electronics as a demand in the Appliances Factory.
This will expand the appliance chain, making it complex like the car chain.
You say your goal is to bring as many industries as possible in one place, and for visual aspects, I say from a player point of view, it's the successfulness of completing complexly, that's the player goal here, like the car and appliance chains. It'll be quite a challenge bringing all those cargos together.
PS, I still think all ore industry capacity needs to be scaled back to vanilla game.
