Ninja Gaiden II

I played Ninja Gaiden for Xbox until I wore it out.  I think overall I went through and beat the game 5 times, which if anyone's played it knows that it's a long game.  I got NG2 in from Gamefly and the only way I can describe it is that it's NG1 on crack/acid/mind altering drug. 

If you liked NG1 you'll love NG2, check it out!
