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. And while I wouldn't object to the option, I don't really care about fighting in this setting. I just want to build out a Dyson Sphere.
"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
To get more specific, I think it would be fun to build out a single O'Neill Cylinder within a Dyson Swarm. For multiplayer, just give everybody their own cylinder. But I definitely don't just want an overhead view. I want to build a little world that can fully explore in first person. And no damn microtransactions! The only exception I'd accept would be paying for other people's models.
