After quickly reading through the suggestion forums, I wanted to show what I came up with while playing this game.
For starters, here is a list for ideal Stations.
-Outpost/Frontier Station: A truckstop in space with general services for those who warped in.
-General Megastation: A city in space that offers all services and manufactured goods, as a result, it will consume raw materials and be an ideal destination for trade runs. However, it could also only produce manufactured good of a certain type like the stations in Elite: Dangerous. Actually their basicly that. Could also be used as the capitals of factions.
-Space Farms: Space stations that produce foodstuff for the populace of all other stations
-Fortress/Naval Station/Fleet Headquarters: Basically a giant heavily defended shipyard.
The next list has other things
-Mega Station Gate: Basically a huge space station with a giant gate inside of it. Like imagine flying into a gate and finding yourself in the middle of a massive space city.
-Nomads: Gargantuan ships that sell hard to find good and equipment.
-Derelicts: An alternative to asteroid mining and can be found in unpopulated sectors. Basically a giant disabled ship that was obliterated and is now endlessly drifting while surrounded by broken off remains and smaller ship wrecks. A good place to look for higher lever materials. Also pirates to balance things out.
-Ship Graveyards: Basically more huge derelicts in one area.
-Ship Fuel: Possibly for low to mid level energy generators, can be sold from stations that produce it. Fuel can range from hydrogen to uranium and thorium to exotic energy crystals that can be sold from refinery stations as well.
-Capacitors/Batteries: Instead of just balancing the consumption to usage of energy, why not add these things to store energy when your ship isn't boosting or at maximum power usage.
-Docking Cave Entrances: For large stations, they could have hollow openings for smaller ships to dock inside of them, which can be good for those in smaller ships who found themselves in a high level sector.
