Complex Space Sim?
I would love if space flight was made difficult to use. Somehting along the lines of Flight Simulator, where players would really have to learn to fly. This could open up areas for professional pilots, getting skill points for how well you do, and having the ships become more responsive the more experience you had. And it would be great if you could move around these ships too. Set the autopilot and sit back in the lounge section with the mini-bar!
