For me it's simple: If you write something, do it more or less well and listen to criticism.
There's nothing wrong with games where you can only be a man or a woman, but if you give me the option to be one or the other, both have to be treated fairly.
It means that you don't just focus on romances for the Male MC, and don't write with him in mind alone.
Psychologically and biologically, women and men function differently, and we treat the same gender and the opposite gender differently; it's something unconscious.
No one forced the author to make it possible to play as a girl, let alone have male romances, but if they did include them, they should at least treat them fairly.
Obviously, these are things that can be fixed if the players simply tell the author and they listen and decide to do something about it.
