In which I play "Dandy" published in 1983 by the Atari Program Exchange, and written by John Howard Palevich. This is really a fun game. It was almost entirely unique at the time in that it supported as many as 4 simultaneous players.
A straight line can be drawn from this game to the arcade game "Gauntlet", the 1985 game by Atari. It is my understanding that John Palevich worked for Atari in their advanced projects division, but I wasn't able to come up with anything that stated conclusively whether he contributed to the arcade game. Just about every feature in that game, comes from Dandy.
