official Kirby's Epic Yarn cover for USA.
A note from the pre-release section of the wikipedia page.
Kirby's Epic Yarn won numerous awards following its E3 2010 appearance, including the prestigious Game of the Show award from GameSpot and the G4 television show Reviews on the Run. Gamespot also named it as the Best Wii Game, Best Platformer and nominated it for Best Graphics. The game received the award for Best Overall Game from Nintendo Life as well. Additionally, it won the Best Graphics award from GameTrailers, beating out notable contenders like Crysis 2, Killzone 3, and Gears of War 3. GameTrailers also awarded it the Best Platformer title. It was named Best Wii Game by 1UP.com , Nintendo World Report and Kotaku, and awarded Best Character Design by Kotaku as well.
Game Revolution editor Nick Tan praised Kirby amongst other games as a great revival, commenting that unlike the other titles, it completely refashions the character Kirby. He compares the graphical style to Yoshi's Story, describing it as a "ball of whimsy" and calling it a "certified winner" of E3. Siliconera editor Jenni agreed, stating that she was excited to play the game after seeing its trailer, commenting that the game looked great on the HDTV she played it on. GamesRadar editor Brett Elston described Epic Yarn as the "cutest, most charming game" for the Wii. He commented that it was a relief to see something interesting in the series, describing recent titles such as Kirby Air Ride, Kirby: Squeak Squad, and Kirby Super Star Ultra as being stale. While The Escapist editor Steve Butts was largely disinterested in Kirby's Epic Yarn in the face of bigger titles such as The Legend of Zelda: Skyward Sword, Donkey Kong Country Returns, and Metroid: Other M, he stated that after playing it, he felt that it was the strongest title amongst Nintendo's E3 lineup, citing the visual style and gameplay.
SO far, it seems like Epic yarn might be the best!
