Dig Dug

I heard about Dig Dug before I ever saw it...the insanity of this game actually matches my imagination of its' insanity based on the description I had heard.  The main character inflates his enemies with a bicycle pump until they explode.  THAT is good stuff, and when I finally saw the game in action I couldn't believe that advance reports had been correct.  You can also create tunnels under the rocks and drop them on enemies skulls, and that is also pretty entertaining.
