Super Mario Galaxy 2

Super Mario Galaxy 2 expands the gravity-defying platforming of its predecessor across dozens of imaginative spherical worlds. Mario uses the Spin move powered by motion controls to navigate upside-down surfaces, launch between planets, and solve environmental puzzles. Bowser Jr. kidnaps Princess Peach, forcing Mario to collect Power Stars across galaxies with help from Yoshi in certain levels. The game introduces creative power-ups like the Cloud Flower and Rock Mushroom that unlock new traversal mechanics. Standout moments include riding Bullet Bills, orchestrating planetary gravities, and the final showdown with Bowser. It's widely regarded as one of the Wii's finest titles for its inventive level design and joyful sense of exploration.
