Ninja Gaiden Sigma

This was a pretty good game.  One of the hardest video games, i have ever played to be honest.  I had to play it for over a month straight just to be able to beat it the first time through, and i never got past the  7th level on the hardest difficulty setting, due to the jump in difficulty this game had.  if you think you are good at video games, and want a REAL challenge... i would play this game to test your mettle.
