I really like the idea of oxygen, and I like the idea of air pressure and decompression, but I don\'t like the idea of massive life support cubes needing to be added. Life support systems and blocks should be needed, and we should have a life support computer and the cubes to be linked to them, but you should not need huge numbers of them. I like the idea of ventilation, but really at that point I think it gets a little too complicated. Don\'t get me wrong, I would love to have this level of realism, where we have bulkheads and airlocks to keep air where it should be and vents to circulate, but the idea behind a game like this is to make it widely available, and I think many people would not be on board with that level of complication.
Forcefields are a really good idea to prevent air loss. I think an oxygen meter in space is a really good idea, and I also think that having air in the void of space seems too campy for my taste. The meter would have to be long enough that being caught outside unexpectedly wouldn\'t be instant death. Maybe air tanks in your inventory that tick down?
Also, random planet spawns are fun for people who want to build their own little empire, but it would kill it for people who are looking to be social and join an existing faction. Most servers i\'ve played on tend to naturally form a \"Core Sector\" where the most powerful allied factions are, and in a very old server a new player could log on and get a nice fat 50 sector flight in a ship with 6 engines attached. Not fun. I\'m in favor of a central invincible space station for spawn.
