Wow, this game really looks better all the time. Unfortunately, there are too many other games higher on my list of priorities over this one, DCK, Black Ops, Fallout New Vegas, etc.. But I will eventually pick this one up for sure, maybe during the slow period of early next year.
I do like to hear how they are trying to bring in an emphasis of great, atmospheric music. I think the aspect of great music in games is one that is highly overlooked. For my money at least, most of the great games have outstanding music. Secret of Mana, Mario RPG, Mario 3, Oblivion, Donkey Kong Country, etc. Games are very much about atmosphere and being taken into a "ride" so to speak, and music is one of the key tools that accomplishes it. Just look at Star Wars for instance. I really believe much of its popularity came from its epic soundtrack, which added to the rich lore of the universe.
I also appreciate the 2D sidescrolling elements, which most developers have abandoned these days. Wii needs more third party games like this!
