Ok, I don't know how the letter gradings work exactly, so I think I put the wrong one for Ninja Gaiden 3, but I think it is a decent game. The graphics are good, the weapon variety is fine and they feel different when used, the plot is wacky but does not disturb, the extra content is there and the controls are ok, use of the gamepad is low but not a total waste. My biggest problem is the difficulty curb, because it lacks one, there are parts that are very hard and then very easy, then nearly impossible, and so on, there are too many spikes and lows on that regard that can make the game frustrating.
In theory the game is short (only 7 hours, from start to finish), but you need to play some sections so many times, that you might be using more than double of that to finish it. A solid 7 out of 10, or whatever letter that represent in your grading system. I bought it for 25 U$ and it was worth it.
