I enjoyed the game up to a certain point. My favorite parts where the secret levels.
FLUDD was ok as an addition but was no reason to remove some of Marios previous capabilities, like the long jump.
I put that game down about 4+ years ago and just picked it up again a few days ago. I didn't remember the button layout, so just played from what I remember(Mario64). I didn't realize I was only a few stars away from the end of the game, but it was a constant fight with the camera the whole way. It made me remember why I put this game down so long ago in the first place.
Its not a bad game, but it wasn't the sequel to M64 that we all hoped it would be. SMG was more than enough to make up for it though.
