I would actually like a Zelda Game to focus more on female characters they actually have. Impa, depending on the game, is either a kick ass warrior or a magical wisewoman. Honestly, both seem like cool game protagonists to me. It's not like Zelda games haven't strayed from having Zelda actually in them ... (Link's Awakening, Majora's Mask) ... Why not actually take a bit of time to do some narrative on already existing female characters, that otherwise merely serve as supporting cast in every other game?
Here's a simple pitch. Have a game set before the first Legend of Zelda where Impa, as a kick ass Hyrulian warrior, is facing increasing qualms about the growing strife in the land. She is faced with the unenviable position of being Hyrule's greatest warrior, but acknowledges how time is working against her. She is getting older, and the true challenges that await Hyrule will outlast her ability to confront them.
She has a vision that one day, she will find a young boy who will successfully bring Hyrule into an era of peace. Armed with said knowledge, and also so armed her enemies, begins a big long quest to protect Link's family. Ultimately spending her few remaining years of being a physically capable warrior facing near-infirmity protecting the one best hope for Hyrule. At the end of the game, you could even have Impa now aged, teaching Link a few moves ... sorta as if vengeance by proxy. It also suits the theme of reincarnation and sense of one era flowing into another.
See, that would be a cooler type of game than simply exploring the sexuality and gender identity of a protagonist who was originally designed to mute, history-less, and (originally) nameless, who functioned merely as a vehicle for one's immersion into the game.
Legend of Zelda already has some good female characters. I'd rather have a story about them rather than simply a female link. Because in the end, it's merely taking a male character, making them female, and keeping them nameless, history-less, and muted.
Why not a vocal, former supporting character who ACTUALLY HAS character, history and a set-in-stone name? Someone who starts off as brash in the game, but then grows more cunning, wise and reserved as she realises that she will likely die before seeing Hyrule gleam once again.
Death, coming to terms with infirmity, honour, duty, and most importantly about the necessity being a torch in the dark so that others can continue her journey. For all those who played the first Zelda game when it was released, all these elements are things we're facing. We're in our thirties or older, possibly having children, and we're at the mid point in our lives where questions about the future and how we are going to face that future is natural.
It would be nice to see a character emulate these qualms and queries. Impa could literally be the character that emulates the questions that the aging gamer demographic actually has.
