The combos and moves, as well as graphics, looks great and must have when it reaches US shores.

I like it showing how the stylus works with utilizing attacks, moves, and combos without D-pad and buttons, and, more importantly, the girl is really cute when she plays.

Which goes to prove, gamer chicks always rock!
