Here's an idea I had after the local economy thing was confirmed.
- Only allow constructing buildings on planets you have built something in orbit first.
- Only allow primary stations around landable planets with slots. (except asteroid stations)
- Allow orbital relays, satellites or comms installations to transmit the economy effects of whatever they're orbiting to another planet
- Otherwise building around stars/gas giants isn't feasible and shouldn't be allowed at all.
- Allows for more customization and even retooling.
- This could be limited to a station being able to receive 1 of these signals and the effects of relaying only becoming active at the weekly tick.
- Could also be limited by forcing the player to build a receiver on the other end, using up another slot (this would still result in many unusable planets).
- The primary station could be special and able to receive 2 signals (one for the station and one for the nav beacon)
