I'd like to offer another thought. Not to shoot down your idea, but I feel like space flight would play out with autopilots involved. What I mean is: The area around a planet, or series of moons (Since you can't "land" on Jupiter) is flyable and can freely control your ship, meaning there could be epic space combat battles just to get to a planet/moon. However, when you get close to entering an orbit of a planet or moon, the game will ask if you would like to land on the planet, and possibly present you with a few Landing Zones to touch down on (therefore allowing the randomization of ground zones). The game will then take over and show you how your ship passes through the atmospheric wall, followed by its landing sequence, with your character hopping out of their ride and onto the LZ. The same could be said about long distance space travel, or LDST (too much for an ODST joke? Okay...). Once you reach the edge of a map, or a point where nothing lies in your path, an option appears to "Insert space travel name here" to another location and then a cinematic (aka load screen) initiates where your ship (and possibly the ships of your buddies that tag along) will enter "Insert space travel name here". There's nothing wrong with this idea, as you still have space combat near planets. It's just less likely that there will be atmospheric battles, and manual atmospheric entry just feels, to me, to be a bit too much. Again, nothing wrong with your idea, and it's all theoretical right now, so I will be impressed if they can pull off your idea.
