Meebzork is one of the more unusual prototypes for the 5200. With its unique mix of action and adventure, Meebzork is as close to an RPG as the 5200 ever got. However did you know that there were two completely different versions of Meebzork created? Meebzork was originally a fast paced shooting game before being retooled into an adventure game. This is unusual since many prototypes get retooled after play testing, but few ever get totally redesigned like Meebzork.
