I want to build various types of orbital and planetary megastructures like Isaac Arthur describes. Ixion has been the closest fix for me, but I want much larger structures than just a Stanford Torus. No idea how Ixion ends yet. But I’d like to see a lot more interior space available, vastly more green spaces, and experimentation with other styles of governance than capitalism. I want to walk and fly around whatever I build, preferably in VR.
“Dyson Sphere Program” exists, it’s more focused on factory and logistics management. But the games central progression is to go from small factory to a Dyson Sphere powering multiple solar system
