I like greebles because space is a vacuum and there's no drag. Too many series have spaceships that are basically fighter jets in space. Greebles are common on things like Star Destroyers (which are really more battleships than destroyers) and on Star Trek ships. But, the Star Wars ships look too much like the ships you'd find on water. The Star Trek ships at least have a unique look with their warp nacelles. But, the skin of the ships is too smooth. A real ship would probably be more like the ISS than the Space Shuttle, something that never has to worry about air resistance.

The Expanse is one of the few that has reasonable space-shippy type ships. But, even then, they imagine a kind of conflict with ships boosting around at high G. Real space combat would probably mostly be long-range sniping rather than manoeuvring. There's nothing at all to hide behind in space. If you can be spotted thousands of km away, why would there be any high-G maneuvers at all? Also, why use chemically-propelled kinetic slugs rather than lasers or particle cannons or something. Space is huge and speeds will be vast. Hitting something with a bullet sounds incredibly hard compared to just using a beam of light.

I may be an audience of 1, but I want some near future hard sci-fi combat without FTL travel but with in-system battles.
