2 other friends and I just finished it up, I have to say that it is one of the greatest games I have ever played and by far the best Wii game yet! We didn't 100% it just beat the final boss on a quick runthrough.
My main problems with it were the 2 toad characters having no name and not speaking english, but it was alright.
The game play was AMAZING, by far some of the most creative and fun bosses in a Mario game and one of the most brutal and epic final boss battles ever.
What is everyone else's thoughts? I absolutely love it.. and the red case was a nice touch!
