He's cheating a bit with Stamets and Culber though, he compares Stamets to a character called Maciek even though Maciek isn't the boyfriend of Aziz (who he claims Culber is "based on".) The actual boyfriend really looks nothing like Stamets:
He also compares a character named
Natasha to Tilly based on them having a similar hair color and facial structure and no further connection. In fact Natasha is apparantly a rival/love interest for "you". Tilly's actress probably didn't rip off this game with how she looks all the time.
As for
Yolanda, she's a communications engineer responsible for all inter planetary messages sent and received to and from Marsi-3, which is some station. I'm honestly not quite sure where I got her being a sort of lead, nothing from her character bio on that guy's website suggest it and the Natasha entry suggests that the player is the main character (in a "customize" way, of course the player plays the most important character) Oh, and of course Yolanda and Burnham have no similarities beyond being black women.
