"Just the facts, ma'am." I know, different television show, but it's the angle that Modiphius took when creating the Star Trek Adventures Rules Digest. It's a new, more compact version of the rules for the sci-fi RPG and you can get your copy, in either print or pdf, now from their website.
From the website:
Star Trek Adventures takes you to the final frontier of the Galaxy, where new discoveries await the keen explorers of Starfleet. Your duties may take you to the edges of known space, or to Federation colonies in need, to the borders of neighboring galactic powers or into the eye of interstellar phenomena.
