Pirates vs Ninjas: Dodgeball is kind of reminiscent of the old Super Dodgeball on the NES. It's not a bad game, but it doesn't keep my interest. The story is weak, the controls make the game pretty repetitious, and before you know it, you've beaten the game.
There are a few additional character types to choose from aside from the obvious Pirates and Ninjas once you unlock them.
Try it for yourself, but I personally would have liked Super Dodgeball on the NES much better.
