INTRODUCTION & GAME STATUS
I would hazard a guess, that one of the earliest gaming memories for any 80's child would have been Hunchback, or any of its unofficial variants, since it was an arcade classic ported to almost every imaginable 8-bit home computer during the first half of the decade. I certainly got to experience Hunchback on the three main 8-bit platforms of my childhood, but principally on the Commodore 64, since that's what I, and most of my friends had in our area.
