Galaxy is garbage and the main reason the Wii sucked
Super Mario World >>> Super Mario Bros 3
Nah, 3 was better. 3 had better challenge, more variety with its worlds, and the GOAT powerups. Most of SMW's levels had the same 3-4 tilesets and it was too easy to cheese your way through the entire game with a blue yoshi or a cape with zero effort. Oneshotting every enemy and flying over whole stages at a time
(I know 3 had the P-wings, etc, but those were rare secret items that you could only get in limited supply. The smw cape showed up in practically every other level from the second world on)
On topic, Sunshine was good, but had some serious issues. It would have been goatworthy if they had retained more of his old moves from 64 (punches/kicks, long jump), dropped the blue coins and included a few more levels with a harder final boss. (There should have been a new villain instead of Bowser IMO)
It's too bad, because I liked where they were going with it. The atmosphere in that game is

on so many levels. It was crazy how every stage you went to, you could see other stages in the distance.
The water effects

The fludd-less levels

EDIT: The swimming controls in Sunshine are also a lot worse than I remember. It's a shame...
