Liza Daly writes: "I'm fascinated by the fertile period between '79 and '83, when computers and consoles went mainstream and hundreds of game companies sprung up overnight. These developers were often obscure — sometimes just a P.O. box and a single teenager — but a few racked up enormous profits. And while there were no real rules yet, there was one agreed-upon convention: graphics were primitive and were never to be shown on the cover. This led to an awful lot of experimentation, for better or worse."
