Huh. I actually believe that Super Mario Sunshine is overrated. For every post criticizing the game, you get fifteen "Super Mario Sunshine is underrated" comments along with it.
I agree that the gameplay is fun, though I think Mario is a little more slippery compared to 64 and Galaxy. The story definitely sucks though, I would have taken a regular Peach kidnapping plot than the one they came up with here. So many plot holes...
Anyways, on topic: Shadow the Hedgehog. Something about the amount of story routes does make me excited to play through the game multiple times, though I understand it's not a popular opinion.
