Yeah, I want to have a jetpack factory. You never need more than 2, but why not have thousands? The problem would be charging them all.I like to build factories. Yes, to make stuff, but that's not why I make them. I make them cause I want to. Nothing optimized, no super tight space that makes it difficult for me to change something, just a big factory.
Energy, on the other hand, does not relax me. I get all crazy when getting my first energy bits up. No, I don't want to waste materials, so the first thing I'm gonna build is a HP boiler. After one Steam Engine (or sterling if I'm feeling cheap)
