I agree with GamePlasma all the way... The wii version kicks ass! I love the new missions and the fact that you can control Jimmy just as easy as that (by swinging the Wiimote and the Nunchuk). I love the new Music class too (I love it in real life), but Geography and Biology... uuuurgh! I nearly (being seriously honest) nearly vomited when I saw the frog in Biology. I skip those classes now.
Another thing I hate is more midgets. Especially those f**king ELVES!!!!!!!!!!! I F**KING HATE THOSE DAMN ELVES!!!!!!!!! GRRRRRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!! But everything else is cool.
