I am impressed by the angle of the crater shadows being correct even across several level of detail changes - great surrounding, graphics team.
Will the dark side of planets be properly dark, especially further away from the core?
Will the amount of light provided by the main system star vary with distance from that star, so Mercury would be blinding whereas Pluto would be rather murky even at midday?
Will the placement of settlements take into account bodies with very long day/night cycles, or that are tidally locked to a star? Can't imagine many colonists wanting to live in perpetual darkness (or the market for Antidepressants and Sun Lamps will be amazing) or OTOH in eternal scorching sunlight on bodies close to intense stars. Would make more sense to put bases around the terminator, unless other reasons dictate otherwise.
