I will now prove you wrong, Yahtzee.
I loved Skyward Sword and none of your complaints about the game proved detrimental to the fun and enjoyment I derived from the game.
And, gasp of gasps, my opinion is just as equally valid as yours is. Not saying you're wrong, or I'm right, but many of the flaws of the game I either felt were so insignificant as to be nothing more than nitpicks or I felt were mechanics that I felt I enjoyed.
You criticize the motion controls? I love them. You criticize the art style? I love it. You criticize the characters and story? I found both fantastic. I felt the world, while not quite as diverse as, say, Koholint Island, was still bristling with stuff to do, games to play, treasures to find, enemies to battle, puzzles to solve, terrain to navigate, items to use, secrets to discover, and much, much more.
You criticize the "sameyness" of Zelda, and I attest that Skyward Sword is more fresh than Call of Duty, Assassin's Creed, Halo, Saints Row the Third, Uncharted 3, Gears of War 3, and so many others, even Skyrim. You say it doesn't change, yet I see a game with a totally new control scheme with motion-control that no other game, not just Zelda games, remotely has that's similar. I see a new world, with new characters, a new story, with new puzzles, dungeons, enemies, items, music, overworld layout, mini-games, bosses, RPG mechanics, a stamina meter, more robust item upgrading, a flying mount, a new save system, and even a totally fresh new final boss. Even the ART STYLE (whether you like it or not) is totally new to the series and extremely unique amongst games in general.
I fail to see how you can claim the game is still so similar when it's by far more fresh, original, and different compared to nearly every other game franchise and their sequels on the market.
