Ninja Gaiden III (NES) Japanese Version (all Bosses)
This is the Japanese Version of Ninja Gaiden 3, far as level, story, and such, it's the same game as the American counterpart. I am showing this, to illustrate how the ideal that harder in Japan is not always so. Ninja Gaiden III in Japan, is the easy mode... less spawns, less damage.
Frankly, it's fun. AKA, Ninja Gaiden without stress. Since it plays the same as the others, it would also serve a good entry point before challenging the regular hard games.
