You could call it serendipitous that Nintendo delivered one of the best-ever entries in this beloved adventure franchise during The Legend of Zelda's 25th anniversary year. But nothing in this intricately built escapade happened by chance. Skyward Sword evolves the series' trademark elements by letting you inject some individual style into how Link achieves his goals and by extruding more of the game's puzzlelike environments into the larger world. The top-shelf game mechanics get help from the sharpest Wii motion controls yet and a watercolor aesthetic that makes you feel like you're adventuring through an Impressionist masterpiece. The first-class creators at Nintendo say the Zelda games form a saga that repeats through history. With Skyward Sword, they've crafted a classic that should stand the test of time.
