Belts were the part of the factory game that bothered me most. You placed them like furniture, piece by piece, and it was never quite obvious which end of a machine was its input.
So step one was clarity. In build mode every machine now shows IN and OUT frames, on the ghost too, so you see how things will connect before you place them.
Step two changed how belts are built. Brandt, the machine supplier, now sells a Conveyor Tool: a slim tablet in a yellow case that you hold in both hands. With it you click a machine's output, look where you want to go, and click the next machine's input. The belt is drawn between them, with curves that adapt to the room. Every metre costs money off your BuckUp account, so a tidy layout is also a cheaper one. If you have played Satisfactory or Factorio, you will feel at home.
The other big addition is the rack crane, an automatic storage system. A belt runs into a station at the head of an aisle, the crane drives down the aisle, rises to a free place and slides the pallet in sideways. Every rack along the aisle belongs to it, on either side, as many as you like, and goods of the same kind are stored together.
The same night I added a whole set of machines for mass production and the bulk buyers that go with them. That one deserves its own entry once it has been played a bit more.
