The thing about Ninjas, is that it has been over done. I like Ninja, but I can pull up any Ninja game, and it will be the same yawning exprience.
Dynamite Deka 2 ( WHICH NOBODY HAS SAID YET....Mhhwwhaaa ha ha ha ha ), The whole entire game ( so far ) has been nothing but me, on an cruise ship, beating the hell out of pirates. It has cannon balls, knives, swords, and they are even wearing the actual hats, that comes off?? Even one cut scene is pure Pirate cheeze that was pulled out......
