Whatever the creator says.
I don't get the obsession over Link's sex, honestly; I would prefer a Zelda turned adventurer.
Same so much. Not only is it not suddenly altering a characters gender, it's developing another and opening venues for different gameplay styles.
You want a character creator, play an MMO. FFXIV constantly reminds me of Zelda, I'd recommend that.
Imagine if a group of people bullied Nintendo about Samus being a woman and aggressively demanded that they made a Metroid where Samus was male.
Same again. I like my Samus female and my Link male. You can argue as much as you like that they're "buhlank slates with no character", but that doesn't make it true. Character is more than spoken words.
