Space is messy, and when the vicinity of a blackhole, not only should it look more terrifying (accretion disk viewable as it devours a nearby star, but it should cause a nearby commander extreme distress, or death if too close. Asteroid fields, have rotating rocks, but no collisions between rocks. I'm not saying have it be a huge field of 500 rocks colliding, but perhaps a few slow moving 'rogue' asteroids would collide into others occasionally so that a commander has to keep on their toes when mining. Neutron stars are just as bloody terrifying as blackholes, perhaps adding updated effects, and 'player status effects' to enforce the idea. Lastly, it would be nice if you added "proto" solar systems, these would be solar systems in various stages of being formed, so there would be partially formed planets and moons, volcanic plannets, lots of space dust, and fields of asteroids coalescing into planets. The universe is a chaotic place, at least some of the systems should represent this! Thanks for listening.
