That is nowhere near enough. The best case scenario is a static world with simplified stelar objects. So far the only released game that got even close to realistic distances was I-War 2:Edge of Chaos( awesome game btw ) which was static.
Frontier: Elite 2 from 1993 and Frontier: First Encounters (Elite 3) from 1995 did it way before I-War was even a thing, complete with full freeform seamless landing on planets with real celestial mechanics.
I took a look at some game play videos and I'm positively surprised. I seems today's developers mostly just don't care or don't have the required knowledge.
Also considering the lack of exposure and the amount of flack Elite: Dangerous is getting compared to the other space games it's also the gamers who sadly don't care.
Btw here is an interesting interview with David Braben somewhat before the time of Frontier: Elite 2's release.
There is also an impressive universe simulator called Space Engine and they are planning on adding gameplay to it, but it will probably take a long time before it's ready.
i dont think its impossible or that they don't have enough money - just that they will fail to deliver based on their having been plenty of time and money for Elite 4 already... it already puts duke nukem forever to shame imo.
i would like to see it, but i don't think its realistic (i don't believe its technically impossible - especially with that kind of resource, i just have little faith in the people involved by this point - which is a shame)
