Ninjas may not have guns or huge swords, but they have the ability to dodge them, disarm pirates, and teabag their bearded faces.
The lack of good ninja material can simply be explained by the awesomeness of ninjas. The true ninjas are too stealthy to be captured in any form of media, so good ninja material is scarce.DanielDeFig said:I guess i should blame Pirates of the Carribean and One Peice for my decision to immediately support Pirates whenever this question comes up, but maybe you can also blame the lack of good ninja material recently (still haven't gotten around to playing Ninja Gaiden).
