This game (rightfully) gets a lot of flak for its jankiness. And it is janky in a lot of regards; there's a lot of bafflingly obtuse levels, like the one where you have to collect red coins in a pachinko machine with positively Euclidean physics. However, at the same time, Sunshine does an amazing job at creating a cohesive mood, a "vibe" if you will, in a way that none of the 3D Mario games do. I love how every world has its own unique spin on the tropical theme, and because they're all located in specific spots on the same island, it creates a sense of place. You get the sense that this is a physical location in the Mario universe, where people live their lives and go to for vacation. Because of that, it's just a blast to explore the levels searching for secrets, especially since Mario is incredibly mobile thanks to the addition of FLUDD and the spin jump. Also, for a Gamecube game released in 2002, it looks absolutely gorgeous - the water effects still hold up even today.
