I chose this area because I thought that I'd have room to automate all the super early game mats and build my space elevator. Now I'm not so sure. Right now I have iron plates, iron rods, screws, wire, cable, and concrete automated with smelters ready to set up copper sheets the next time I play.
When I posted that comment I hadn't realized that I already unlocked walls with base building. I thought that they were in the shop, and I'd have to use foundations as walls until unlocking them.
Yeah you get the bare essentials with the main path, and then cosmetics are all through the shop
