An idea occured to me... the beacon/gate/flower are "things" that take one tile, and that tile can't be used for anything else... maybe stations could take space in the same way, instead of working like a city? If that could be done, stations wouldn't take sweet spots that would be perfect for settling. Instead, ALL stations would ALWAYS ask for a player/AI permission, and then spawn at a player/AI designated tile [like the "things"], inside our/theirs territory.
Now that would be ace, and even more reason to go a bit wide empire!
