This is a good 3D Mario, with good level design and interesting worlds to explore and complete. The biggest problem is that, exploration ends up redundant. There are too much moons that you just step on sometimes, the clothes and coins dont do anything.
BUT
I really loved this game much more than i thought i would. The music, art style and dumb writting are amazing. I like how the game plays as a silly cartoon, and i really love the trip around the world theme. The music is also superb. Really, a solid game.
