Super Paper Mario

Super Paper Mario is the third game in the Paper Mario series. Though the last two games were mainly an RPG game, Super Paper Mario will be centered around Platforming, and will have RPG elements. In this game, you'll be able to take controll of Mario, Peach, and even Bowser. It was actully supposed to be launched on the GameCube, when it was later merged over to the Wii in September of 2006. While the game was thought to be a standard 2-D game, it was soon revealed that 3-D elements will also be combined with the 2-D elements to make a brand new type of game.

Playable Characters
Mario - It appears that Mario will be able to switch the view from a sidescrolling perspective, to a 3-D one, making him able to solve unsovalbe puzzles.

Peach: Peach will not only be able to jump the highest, but will also be able to use her parasol glide much like she does in Super Princess Peach, Super Smash Bros. Melee, and Yoshi's Island DS.

Bowser: Despite him being the slowest character in the bunch, he will be the strongest. He will also be able to blow fire, which apparently deals more damage then regular attacks.

Themes

 * Grass theme - A standard grass theme that you would expect from any Mario game.
 * Oasis - What seems to be an island right before the sun sets in the background.
 * Cave - An underground cave.
 * Underwater - Underwater area. It seems that a giant Blooper will appear in this area.
 * Outerspace - An area where Mario (or any other team member) flys through space.
 * Mountain - A mountain, not much is known about this area.
 * Sandy theme - Here you will encounter the giant dragon boss shown in the videos.

Plot
Though not much is known about the plot, there have been tidbits confirmed through multiple sources. The first one comes from a recent issue of Nintendo Power, which confirmes that one of the enemies (possibly the main antagonist of the game) is named Count Bleck. Mario also seems to have traveled to an area called Flipside in between dimensions. Flipside also has a giant black hole above, reasons for this are also unknown.

Gamecube to Wii
The game was announced to be released on the Gamecube. Though because of the death of the Gamecube, the game was merged to the new Wii console. It was also announced that the game would use enhanced Wii controls.
