I would like to see Factions and Ownership of objects very soon! I like the way Minecraft has their PVP set up. When you have a faction, you can declare war on other factions. But because of many time differences, Minecraft will give the opposite faction 24 hours before they become hostile and attack-able. But we would need dedicated servers with 32+ players. Also, I would like to see pressurized interiors! Being sucked out into space through a hull breach would be epic. This would be very crucial during an hail storm of asteroids or even a "sun" storm like high levels of radiation. Tractor beams would be cool too! For example, towing another craft using landing gears has been a bit shady... I get nervous being that close to another object when in survival mode. Tractor beams can make towing easier from a distance. To make tractor beams rare, you would make it have many parts and burn large amounts of energy. I play a lot Kerbal Space Program too... Kerbal is a rocket simulator, so you have many "look a-likes" of apollo style rockets. Decouplers are very crucial when trying to get into space in that game. But they also have many practical uses... carrying extra equipment, engines, living spaces, fuel, ect ect. Also, "docking" ports would be cool. In kerbal, they have many different types of docking ports.. these are magnetized just like the landing gears in Space Engies. If you could make a component to dock ships together in space without the use of a landing gear on the hull, it could make ship boarding and sharing easier. For example, many times Ive tried to land in a carrier I made in creative causes many bent blocks and hull breaches... the component would not be able to bend when another component hits it. Lastly, NPC's or some sort of space monster/ faction to defend against would be awesome.
