What's being discussed is hardly even a "realism" thing tbh. Some things are just not consistent with the game's own canon.Well it is very possible to do a game that has realistic relations so that people can relate better to it.
Batman's hardly realistic, but it would still be pretty jarring if Bruce Wayne's parents got kidnapped by the Joker.
Before Dakota's most recent revamp, one of the first doses you gave her would have her divulge to you how sexually frustrated she is and how she never has time for sex. Her being a prostitute is a recent development and a massive pivot away from the original lore.it's like if the dev didnt think the evolution of the relationship early enough in the game conceptualisation and developpement. So he is stuck with this relationship that he must make work with the entirety of the game mechanics.
