One of the sleeper hits of this years E3 was Super Paper Mario, doing what New Super Mario Bros. has done for the DS for the Gamecube.

With is unique perspective, the game is essentially a classic Mario platformer but with a twist of being able to switch into 3D at any time. Along with the view switching, you can also flip between Mario, Princess and Bowser at any time.

These videos of a the game have appeared on YouTube having been recorded at the World Hobby Fair in Japan. Apart from Zelda, this game could possibly be the last great game for Gamecube.
