Single Solar System As Outer Space Roleplaying Setting

I have previously described the Rhydinspace plane/dimension as only a single solar system. I am embracing this preexisting lore as an inspiring limitation. This is more than enough real estate for an outer space roleplay campaign.

A single planet can be challenging to a gamemaster as a fantasy setting. Eight planets with numerous satellites and a single star is a truly intimidating canvas size to me. And that is before adding magic and travellers/immigrants from other places. I am not even thinking of space stations here. (Asteroids? Yes, please!)

Galactic Scale is wide but usually shallow and homogeneous. My aim with Rhydinspace is depth and variety.
