Like, Ninja Gaiden Gaiden Black is possibly my favorite game of all time, so I'm not going to argue hard with you here. Ninja Gaiden 2 isn't nearly as polished as black, but the depth of combat options, attacks, and combos available, along with the significantly better and more varied weapons, the extraordinarily bloody and vicious battles, and how exhilarating it is to take on 6 Ninjas at once, nevermind many of the later combat encounters make it my favorite combat system. There are some cheap encounters though (rocket spam), something you would never see in Ninja Gaiden Black, and the Boss Encounters while always cool, and somewhat broken and cheap at times. Black is certainly the better game.
