The 3D Mario games just seem to get better and better as they go.

The environments in this game are so densely packed with things to see and do. Each one has its own unique feel, and you can tell that the level design was very intentional. The controls are responsive and fluid (okay the shaking thing is a little annoying).

For me, this is currently the gold-standard for 3D platformers and collectathon games. A must-play for anyone who enjoys this type of game.
