A good game that will mostly appeal to hard core fans. I'm just glad they don't have goblins or ghost in them anymore.
A nice feature is that you can customize your ninja, similar to Frank from Dead Rising. You earn money and can purchase clothing, armor, or even a bird that sits on your shoulder as you decapitate your enemies. This game isn't hard, just long. I am a fan of the series, and therefore will buy any new editions. It does provide some realistic ninja moves and action. The AI isn't the smartest either.
The best part of the game is the way or manner you neutralize your enemies. Everything from blow dart guns, explosive mines, straight out combat to amazing stealth kills only described as "oooooo"
I gave this game a 8.5 because I love the series, but I would recommend anyone to rent before own.
