THE MOST INTENSE AND MANLY GAME EVAR.
Also the BEST game EVAR. Frankly, I can't get enough. Now just about every game I play that has a customizable character is SUPER VIKING. After beating 3 of the songs on Easy, and A Storm So Calm on Medium, I beat Speedway on Hard on my first try. Please, PLEASE make more. I could see so many great songs fitting perfectly into this game. Also, for drummers (such as myself) and other rhythmically talented people, consider adding a "MEGA EXTREME" (or similar) difficulty, pulling no PANCHes. With more songs and higher difficulty, those unworthy of playing a game of this intense manly-ness and sharkicide would simply explode.
I say it again: THE BEST GAME EVAR.
