I am so ridiculously pumped for this. At first I was slightly disappointed after some of the 8's, but after having time to digest it I'm not too worried about the concerns.
Linearity and only
main areas? Better than a huge open empty world like in Twilight Princess
Upgrade system is optional? Better than having the only reward from side quests and treasure chests be rupees and heart pieces
Silent Realm? I have a feeling I'll be on the side of enjoying the intensity of them
Lack of exploration? Better to have a cohesive and well paced experience than throwing in random nooks and crannies just for the sake of it. To be fair, I definitely understand why some people are upset by this, but I'm sure it was an intentional choice, a different direction the creators wanted to experiment with.
Harp is too basic and not as fleshed out as instruments in previous games? The intent then was obviously to not have this be a primary game mechanic. I'm assuming it will primarily serve story purposes, which is fine with me
Backtracking? I love the Metroidvania approach when it's pulled off successfully. It seems like that is the case here
Fetch Quests? Yeah, fuck that
These gripes with the game I understand will frustrate some people, but knowing my own gaming preferences and what I like/dislike, particularly in Zelda games, I don't see these bothering me all that much
So with the flaws that will probably end up being very minor to me anyway being heavily outweighed by all of the outstanding qualities of the game (graphics and art style, soundtrack, combat, story, pacing, length, and a grand sense of adventure) this will seriously give Arkham City a run for its money as my GOTY. And I fucking love the shit out of Arkham City, it immediately became one of my favorite games ever.
As a long-time Zelda fan who owns and has beaten every game in the series, I am most excited about a Zelda game finally feeling "fresh" again. Sure, some of these advances are going to come at the expense of certain franchise staples, but if you want to revisit some of the elements this game doesn't have you can feel free to replay the over two decades worth of games from the series.
Also, none of this is to say that I won't have my own complaints about the game. I have issues with every single Zelda game, and in fact, every video game I've ever played. I've yet to experience a completely "perfect" game that has no room for improvement, yet I know this is because perfection is an abstract ideal that is rarely, if ever, attained by the arts.
So yeah, bring on more 8's, throw some 7's in there too if you must. It doesn't matter; I am thoroughly convinced that I will love the unholy fuck out of this game, moreso than I have with a Zelda game in quite some time.
