A game about a sigma male that gets bogged down by segments where you're forced to play as a woman.

Jokes aside, Sigma is still very good; the Rachel stuff is really weak, and I do miss the stuff that was cut out, but it's still Ninja Gaiden at its core. Play this one after Black, it's probably a bit more replayable since it focuses way more on the action side of "action-adventure" of Ninja Gaiden.
