You can ask anyone in the chatroom I've talked to recently, I've been very very iffish on Super Mario Galaxy, and the way it played. After getting used to the camera, I felt something was missing from the game. After making my way to the Fountain, and getting to the second Bowser base, I realized what was missing: Suckage.
If we look back to SM64, the best part, anyone will agree, was bowsers castle. When you were in those sections, there were no rules. He could do anything he wanted to you. In return, you could pull off shit there you couldnt anywhere else in the game. It had puzzles that would rape you, and you'd sit there still giggling cuz the fat man fell in lava and was grabbing his ass going 'owowowowowowowowwwwww' then that damned laugh.
However, in Super Mario Galaxy, I knew it felt different. Super Mario Galaxy took what made SM64 fun, and turned it into an entire game. It wasnt till I heard the familiar tune, and saw the red lava, that I realized "Oh shit, thats the entire game. FUCK YEAH!"
TL;DR: Hated SMG, now love. MAKE LOVE TO ME OH SWEET PLUMBER OF ITALY.
