Maybe Ninja Gaiden Sigma 2 should be on the list. They said the Sigma series is not a port.

Who's "they"?  It's the same game that came out a year ago for 360, but with new playable characters.

Ninja Gaiden Sigma 2 features a whole lot more than that. Not only does it feature 3 brand new playable characters who will all be playable online along with Ryu in the brand new online co-op mode, the game also features new weapons, new enemies and large-scale bosses, new branching storylines, as well as a completely overhauled graphics and physics engine and a new camera system as well as subtle but constant detail changes such as less emphasis on blood and gore and more on flashy combos, movements, and techniques. Hell, it's even being done by a different director and team. It's in every sense a remake just as the original Sigma was and it's exclusive.

I also opt for it to be included.
