So the skybox seems to be a temporary solution they have in place just for now while they are working on how the real backdrop will be generated based on your location in the galaxy.
Procedurally created sounds good for nebulae type things. Still want stars as particles if possible performance wise, or some way of treating the stars (i.e. identifiable as only thing with pure greyscale value) so that they maintain size if zoomed (if zooming is in the game of course). Heh, maybe even doubles like Alcor/Mizar separates upon zoom from sol?
Yeah, Space Engine approach to everything would be utterly fantastic. I hogs along just fine pretty much everywhere if limits are kept to my normal eye sight - of course not sure how viewing from space would affect that. Turn up the limits or go visit some really busy place (like inside a globular cluster), or both, and there is a penalty on performance. Of course, Space Engine doesn't really do much else at this point but to render space (little "gameplay" related code).
Other things:
1) Arma2 (a MilSim game, haven't checked in Arma3) have stars are rendered in front of the moon - just don't

Here those things become a bit more obvious of lazy code bugs.
2) Let space be realistic. No overly use of nebulae where we know none can be seen.
3) X3 games; I mean, seriously what is this? "Fog" covering a huge station a few hundred meters in front of you, yet you get to see stars and planets. I'm a SP player only, and I'd rather have the ability to make space "dull and realistic" than "beautiful and unrealistic" (grows old quickly anyways).
