This game is one hell of a trip. This is by far my favorite game on Wii so far. The controls are very simple, but are used to pull off some complex puzzles and classic platforming. I have the other two Paper Mario games, and this one is my favorite. It gets rid of the boring turn based fighting, that i found rather annoying, and instead you fight the way Mario was made to, jump. The story is kind of wierd, but fans of Nintendo will find it funny. The graphics, although mainly flat, are very crisp and clean. The game has a very welcoming feeling to those of us who love SMB3. Now the actual gameplay. I would call this game a hybrid of SMB3 and Crash Bandicoot. I know it sounds like a wierd mix, but it works well. The worlds are seperated into 4 different levels. Each world has a different feel and look to it. You have to go from point A to point B, but unlike classic Mario games, there are alot of puzzles along the way. Many of the puzzles will be solved in one of two ways. The first is to flip into 3D. The 2D Mario will go into the third dimension by just pressing A. Once in the 3D mode, mario can find hidden passages,sneak past his 2D foes, and find special items. The second way alot of puzzles are solved is by using pixels, which are strange creatures that have special abilities. Some are extremely useful like a hand that can hit out of reach switches and grabs enemies and items, then there are those that are pretty useless like a moving platform that makes you move faster. But all are still used. Later in the gane you can play as Peach and Bowser, both useless compared to Mario because they can't go to 3D. They do add to the gameplay though.The game is pretty long, about 20 hours, and there are alot of secrets and collectibles. This is a must have for Wii owners.
