I have only used KiCad and I actually don't see the similarity.

In KiCad you start by designing a circuit schematic first. In Factorio you start building whatever you want. You have potentially have to create your own custom parts including their physical footprint based on existing chips. In Factorio every part is already included in the "part library".

The PCB design phase automatically connects parts with traces correctly. The human designer is just responsible for the layout. In Factorio you keep the design in your head and place each conveyor tile one by one.

PCBs usually have multiple layers and it's common to have dedicated VCC and GND planes just for power transmission. Although the electric grid in Factorio is technically a separate layer, you have to extend the grid by placing transmission lines.

I will accept that the idea of non overlapping traces/conveyor belts is similar but overall the workflow just isn't the same. To be fair I haven't actually done anything beyond following a bunch of tutorials on making PCBs. I have yet to send a design to a manufacturer. It's possible that Eagle and Altium are significantly different to KiCad but I personally stick with opensource tools and even if they may have significantly worse UX I actually love the extra challenge. Just shows that other than paying bills to stay alive nothing on this planet should prevent you from learning electronic design, mechanical design and software development on your own.
