Super mario sunshine is really good.
It has a lot of stupid flaws (some blue coins being exclusive in some missions, too many blue coins in generals, linear and bad progression system, too many red coins padding shine, 2 really bad bonus stage, yoshi sucks, only 7 main levels with too many shines, Corona mountain is bad) but I've also beaten the game 100% 5 times, the core gameplay and the level design is amazing and it has an amazing atmosphere.
It's a 3d Mario game in the end, all 3d Mario are amazing.
It could maybe be a average good game if it wasn't called mario but with some other new character.
The level design, the music is just way off of what quality mario game should be. Even the last boss is really that bad in sunshine. Compare this to the magic of mario galaxy. The level design, the epic music. That's what I want for a mario game.
While mario odyssey is still more of a mario game compared to sunshine, I still hope they will work on a galaxy 3 game.
