Agree, Writing is great and EDI was given me feeling of sci fi theme suit this game as well as it's really humanoid robot unique look. Just don't make it too much human should be fine. (We have human already and i think chip should represent humanoid robot unique whether appearance base on what)I think most players like this game because of the hot setting and good writing, not because they want to fuck monsters / aliens / robots.
It seems that your assumption is since game is a space odyssey then readers MUST like furry-adjacent monster-fucking content. That's just not true.
Galiano is probably popular because his writing is fucking hot and he destroys the MC nice and good during their scenes. Writing trumps looks, I'd assume. He's my favorite and I'm not a monster fucker either.
As far as the android goes, I'd personally choose similar to EDI from Mass Effect. It's just tethering at the edge of getting too unhuman.
If EDI was only one i can hope then go ahead.
At this point EDI still better than human robot that look like too much human to the point can't see different hahaha
