I just beat it. well, not fully beat it, but finished the story - till got goals to do.
overall, i'd say it was a sweet game. i like the changes they made from the old series, but the one thing I didn't like was the turning (you look all noodley and stupid), and the lack of levels.
I know that the other games had about the same amount of levels for the story, but they also had double that of levels from older games for classic. since they incorperated the classic with the story levels i kinda felt a little jipped.
