I thought of making this post on TotK sub forum. But from the trailer we saw that Link isn't customized.
So even though its less likely to happen, how would you take it if Link was a customisable character i.e you can not only change the armour but also his facial features build etc
I think it's an interesting concept! While there would have to be some restrictions so it still to some degree looks like Link, and the race would probably have to be the same for all Links so the game makes sense, I think that this would be super popular! Link is supposed to already not talk and look male or female(depending on how you think about it) because the player is supposed to see themselves in Link and put them in his shoes as a silent protagonist!
We could potentially even make changes while customizing that without us knowing it slightly alter the gameplay! Make Link darker skinned and have hair that's a different color and texture than that of your generic Hylian(for example, if you made Link a black guy), you might have different interactions with some hylian NPCs than if you made Link a white guy(cough rac!sms that lead to Link beating up an NPC cough.) If you make Link shorter there would be more subtle teasing about his height and more jokes about it than if he was average height, but he would be faster and more nimble+agile, but also a more hotheaded character because he's probably a younger teen if he's that short. If you make him super tall, you might get surprised comments from Gerudo Women, and Link might be a little faster because he has really long legs, but also he would be more lanky and awkward, possibly more bulky and rather than being nimble, just physically stronger, and may occasionally hit his head on branches because it's funny.
If you chose to play Link as a generqueer/gender fluid/trans/nonbinary character(in customizations and changeable ay any time, and especially if hes genderqueer, you can change what you want his current pronouns to be that hes using as you play), you can use it potentially to your advantage, being welcomed into Gerudo Town with open arms but it also failing when he needs to go undercover as a gender he currently isn't and is thus u comfortable, making it harder to succed those missions and easier tk fail. If you play a gay character, you can flirt with anyone(no matter the Links sexuality) but depending on your Links and the NPCs sexualitys and wat your Link and the NPCs types are, it is more or less likely to fail.
I have more ideas, but I don't want to take them all so I'll stop here.
