I found they all look they same, just skin tone rehashes on almost identical faces, and maybe different coloured suits to spice it up.
looks like all Crew applicant's are inbred, that or humanity resorted to....desperate measures in it's past....
On a serious note; I wouldn't mind a more diverse feature to choose from, not always 'prettier' but just more varied. and a algorithm for more race specific features to build cultural depth. ( Eg Scandinavian= higher blue or green eye chance, appropriate nose shape and facial structure, Light skin is significantly higher. African origin= high brown eye chance, appropriate nose shapes and facial structure and significant darker skin tone chance.)
At the moment I haven't really seen any NPC's with African appearance AT ALL, just Caucasian skin rehashes and that's it. I think what the current generator does is that it mashes everyone together without considering the fact we differ with origin. and that's the reason why they look "ugly". they have no proper identity!
