Play baseball, except with players represented by SPOGS (Sports Player Object Gyros - no, we don't understand, either). Import your face into the game and play individual games, playoffs and unlock special pitches and more.
Just like all good pirates, you'll be swashbuckling, captaining, boarding ships to take them, swordfighting, sneaking about town undetected, and of course....dancing? Become the most piratiest pirate there is. Oh, and "ARRRRR," and stuff.
