Developer/Publisher: Nintendo EAD Tokyo for Nintendo
The first Mario game developed for the Wii literally blasts you into space to explore 42 galaxies filled with hundreds of planets, each with their own eco-system, enemies, and gravity. Its innovative physics system gives you the ability to jump between and fully circumvent the spherical 3D planets. Hands down the best Wii game ever.
