Ninja Gaiden Sigma II's Mentor, is Ninja Gaiden II's Master Ninja, Mentor is the last mode I completed barely before I got rid of it. I think I have beaten Ninja Gaiden II, (Sigma II and II combined) a total of around 20-25 times, to get different times and learn different weapons. Basically, like I was saying, the other weapons aren't really bad, it's just that I don't know how to use them. For instance like you stated, the Kusari-gama has the potential to be a good weapon, sometimes it takes a long time to attack, because he was to wind up the weapon and spin it around, if I knew how to play with the weapon, I could meticulously judge how to fight with it knowing the given delays of any weapon, knowing delays combined with knowing enemy flaws, equals weapon perfection. All of them are good weapons, I'm just use to using the Staff and Dragon Sword since I've been using them since Ninja Gaiden Black. This guy, xkzerion gave me an example of weapon mastery. Another major concern of mine is Itagaki Tomonobu's absence from the development, I wouldn't be surprised if some of the team members influenced by his ideas were still at Team Ninja, but this "Look into the darker side of Ryu", sounds something like Metroid: Other M, Samus introspecting every cutscene. The joy of the character was that he didn't need to say much, a stark difference from Bayonetta, Kratos, or Dante. I can only hope they do something good.
