Alright here is my list for essential space adventuring:
>hot space babes with different skin color
>hot space babes with different skin color + one head feature like horns or small tentacles
>robot
>one or maximum two actually alien races
>laser guns
>medium sized ship that holds the party and some doodas but nothing beyond that scope.

This is the core of any good space adventure and going beyond that needs to be focused on singe sessions or smaller arcs.
Shit like >>95992498 ?
Cool but keep it to a handful of sessions to explore the concept but then move on.
This >>95995270 ?
Acceptable. I will shot at it for some time until I looted the planet/asteroid where I encountered it but then I will fuck off again.
>players get their hands on an actual major vessel with hundreds of crew members
Fun for a change but after a while it's back to the smaller ship.
