I got the urge to play King's Quest 6 today. I found a copy of it and it's really bringing back some memories for me. It's all stupid and pixely looking. What are some of your favorite old school computer games? A couple more of mine are The Secret of Monkey Island, Commander Keen, Duke Nukem, Wolfenstein and there was one more that I can't remember the name of right now. It had a green monster in it that had red suction cups for hands. 
This is a true classic ,played every were there was a screen and power ...
