If you haven't played Ninja Gaiden yet, you have absolutely no excuse. The game has been released and re-released for almost every game system you could want. Now it finds itself on the Vita, with a little plus added for the sum of all those previous games. You once again step into the adventure of Ryu, as he hunts the fiends that attacked his village and clan. The difference now being on the Vita. You can tap the screen to enter into a first person view mode and tap to fire arrows. There are also new enhancements you can wear, giving you additional power or defense. Or you can play on the forgiving new difficulty if you are worried about breaking your Vita in anger. But that is really all there is. The rest is the same great game as before, now just portable and still beautiful. If you have never played it before, this is a fine version. But if you have, there isn't much new here to justify another purchase.
