Hi,

Just wanted to drop a suggestion / idea

If it's possible, I think the most straightforward way to deal with the space age stuff is to just have each planet be its own warehouse that you can only transfer between in the normal way you would with a planet

So at the start of the game you're in a warehouse on Nauvis, and can only get nauvis resources

Then you build a rocket, a space platform, and go to other planets

Then you land inside a warehouse on each one that can use any of the resources on that planet.

If you want calcite on nauvis for example you need to fill a rocket in the vulcanus warehouse and fly it over or gather it from asteroids

You probably already thought of this but i wanted to just drop it here in case you're still looking for ideas.
