Is gender of MC important?

Alas this thread has been subsumed under ‘Is gender of MC important?’,
which is not where I was headed with my line of questions. I am more concerned to discover whether IF can be turned into something more artistic. But I’ve
read your comments. So new questions. I can see that the
issue of choice, pure and simple, gender aside for a moment, is
critical in game creation. Should the variables of a protagonist’s
character be chosen based upon the desires of the player not the
author? Or put another way does the ‘author’ only have control over
the world, subsidiary characters, and possible events? Does author
have to forego the right to create the MC in order to create
excellent IF? Should IF be exclusively the domain of the RPG?

Okay I’ll stand back and let the bullets fly again.
