Karateka
“Karateka is a 1984 computer game by Jordan Mechner, the creator of Prince of Persia. Karateka was Mechner’s first hit game, and was designed while he was attending Yale University.”
I have fond memories of this game. I played it green screen style on the Apple IIs in the library. Some kid copied it off nine million times and everyone got a copy. First game I ever felt the urge to play for hours at a time and that gave me a feeling of being transported.
