It's interesting to compare the opening paragraphs of IGN's reviews for SS and TP.
Skyward Sword:
"The Legend of Zelda: Skyward Sword is the greatest Zelda game ever created. It's the best game for Wii and one of the finest video game accomplishments of the past 10 years. The game has once again raised the bar and forged new territory for an iconic and innovative franchise. It's not enough that it finally establishes a powerful, stirring origin story or that it features near-perfect pacing. What puts Skyward Sword over the top is its layered, dense, absolutely perfect gameplay that manages to not only nail motion-controlled combat but remarkably offers a stunning level of diversity.
10/10
Twilight Princess:
Ocarina, your time is up. It took Nintendo almost a decade to do it, but the publisher has finally created a new Zelda game that is so well-designed and so epic that it deserves to be crowned the best in its class. Twilight Princess spent four years in development by one of the most talented teams in the world. The game, helmed by Eiji Aonuma (Majora's Mask, Wind Waker) is every bit the culmination of the franchise and also a true spiritual sequel to the Big N's 1998 N64 classic. This is much larger, darker and more difficult adventure than GameCube's Wind Waker, which is sure to please purists. It is also a title that is best on Wii thanks to exclusive gesture-based controls and some added display functionality. But is it perfect? Keep reading to find out.
