I want to suggest another kind of objects for space. The space station, in fact it's a small planet like Gates. To enter, you need to use the teleporter on the ship. Types of stations: 1) Research. Population - scientists. You can buy something rare and interesting. 2) Military. You politely asked to leave. If you do not leave, they start to kill you. 3) Resort. Music, fun, exotic foods and drinks. 4) Abandoned. Horror, flashing lights, monsters, perhaps - the absence of oxygen. 5) Empty. The player can use it for his needs.
