TL;DR
Space platforms can meet each other.What?
I know this could be quite difficult to implement, but it would be interesting if the space platforms could meet each other instead of existing separately as they do now.That is, you can meet another space platform that is traveling in the opposite direction, flying faster, or simply drifting in orbit.
Platforms could communicate with each other and transfer resources, for example via capsules as in a planet drop, or via docking nodes to which belts, pipes and logic could be wired.
