Perhaps for you, Kull, characters deserve no better than "meh," but I'd personally beg to differ.
Take Stellaris for instance. You'll often find players role-playing the lives of various characters in Stellaris (recent example
here), even though they are even more abstracted than in Distant Worlds. Characters in Stellaris do not exist physically in the galaxy as they do in Distant Worlds (on ships, stations, and planets). More so, characters in Stellaris only have one or two traits, whereas Distant Worlds characters have multiple traits and can improve over time. Lastly, each character in Distant Worlds has a history log, tracking the events they've participated in, whereas in Stellaris they do not.
Point being, if players can fantasize about the lives of abstracted Stellaris characters, ones without a physical location, history log, and less personality traits... that says something about the potential role-playing that can be done with Distant Worlds characters.
So, Kull. You don't like role-playing, but that doesn't mean other players don't. Characters, to me at least, were an important part of the playing experience.
