Shadow Dancer (Genesis / Mega Drive)

Anyone who spent at least some of their youth growing up in the 80s knows just how popular ninjas were back then, and if you didn't now you know!  One of the most popular games featuring ninjas during that time was Shinobi.  It had some pretty fantastic arcade action in its day.  For me, though, my favorite was its sequel, Shadow Dancer.  The game had great graphics, fast action, and it was a title that really got me thinking, "This is 16-bit gaming!" when I saw images of it in magazines as a kid.  You even had a pet dog helping you out.  It was a darn good game.
