I played the demo of Super Mario Galaxy at gamestop. Here are my thoughts
-Controls felt disgusting
-in order to do a spin attack, you cant just shake the remote...it has to be pointed at the screen.
-CAMERA ANGLES were so awful! And on top of that, they changed at random!
-graphics didn't impress me. at all. but i know not many care about that.
-controlling mario's movement was about as easy as making an elephant jump
-overall unappealing to me, it felt rushed and unpolished.
