Rebound (video game)
Development of "Rebound" began in late 1973, as one of several variations they produced in 1974 on the gameplay of the successful "Pong" (1972), Atari's first game and the fourth-ever arcade game. Around the same time, Atari launched Kee Games, a subsidiary meant to produce clone games of Atari's products and act as a competitor in order to expand into more distribution channels in the same region than the industry typically supported. Kee's first game, released in March 1974, was "Spike", a clone of "Rebound", which added a "spike" button to the game that made the paddle jump up and attempt to bounce the ball downwards instead of up. In addition to the base game, Atari sold a conversion kit to convert any Atari two-player "Pong" variant into "Rebound", and in 1977 "Rebound" was included in "Video Olympics" for the Atari 2600, a collection of "Pong" variants.
Adventure (Atari 2600)
"Adventure" received mostly positive reviews at the time of its release and has continued to be viewed positively in the decades since, often named as one of the industry's most influential titles. It is considered the first action-adventure and console fantasy game, and inspired other titles in the genres. More than one million cartridges of "Adventure" were sold, and the game has been included in numerous Atari 2600 game collections for modern computer hardware. The game's prototype code was used as the basis for the 1979 "Superman" game, and a planned sequel eventually formed the basis for the "Swordquest" games. The Easter egg concept pioneered by the game has transcended video games and entered popular culture.
