I honestly would love a Zelda in first person like Skyrim, with the option to seitch to traditional third person, like The Jedi Knight games with Kyle Katarn.
I would love a Mature rated Zelda, like how they did Lord of the Rings: War in the North. Problem is I doubt Nintendo would do it because it would ignore a major part of the market, kids.
I could see a different game studio making M-rated Zelda with Nintendo’a blessing, them footing the bill.
