Perhaps, on earth and maybe alien solar systems (if that idea is passed), maybe there can be a few towns/space ports. This could also tie into the multiple locations thing. For example, you go to locations > Earth > spaceport one. If you pass or land at a spaceport or town, they could be added to your locations. Maybe, if you land at a spaceport correctly, the spaceport will even refill the ship! I plus, it'd be fun to ingage in nuclear ware fare on other fictional towns...
