Super Mario Sunshine is still a great game in the current year. Mario moves extremely smoothly, and FLUDD is a fun mechanic. The level design is extremely creative, but sometimes to its own detriment. Some shines are poorly hinted at, or have counter-intuitive mechanics, and sometimes the level gimmicks go too far. These shines come up at least twice per world, and can impede progress for a while. I found myself resorting to a guide a couple of times, but I was mostly able to figure it out. Other than that, this game is fantastic. Mario controls buttery smooth, the levels look pleasing and are very creative, and the music is catchy, yet tracks never overstay their welcome. It's a solid game, just be ready to deal with some older-game jank.
