I think the one thing that impressed me the most is how well they made good on their promises to shake up the Zelda formula. It really does feel fresh and novel while still feeling like Zelda.
As great as games like Twilight Princess and Skyward Sword were, they did feel very structurally familiar, but with this, it feels like all bets are off and anything could happen, which is an exciting feeling that I haven't really felt towards a Zelda title since Ocarina.
Normally I go into a Zelda game knowing what I'm getting, but this feels like an exhilerating leap into the unknown.
Sure, nothing it's doing is a world first by any means, but it drives the series forward in an interesting new direction while reinterpreting tropes from other genres in a very charmingly "Zelda" fashion.
