List of Atari, Inc. games
In 1975 Atari released Home Pong, its first of several "Pong"-based dedicated video game consoles, and in 1977 released its first home video game console, the Atari Video Computer System (later renamed the Atari 2600). From that point onward Atari developed both arcade games and console games, and in 1979 added games for their first home computers, the Atari 400 and 800. Atari produced a second home video game console in 1982, the Atari 5200, and four more home computer versions. Beginning in Summer 1981, Atari published the Atari Program Exchange, a quarterly mail-order catalog of software written for Atari computers by external developers which Atari then distributed to customers. In May 1983, Atari started the Atarisoft division, which produced ports of games by Atari and others for non-Atari home computers. In July 1984, as a result of falling sales due to the video game crash of 1983, Atari, Inc. was split apart by Warner Communications; the arcade division continued as a subsidiary of Warner under the name Atari Games, while the console and computer games divisions were sold off as Atari Corporation.
LucasArts
The first products from the Games Group were unique action games like "Ballblazer" in 1984, and "Rescue on Fractalus!". Beta versions of both games were leaked to pirate bulletin boards exactly one week after Atari had received unprotected copies for a marketing review, and were in wide circulation months before the original release date. In 1984, they were released for the Atari 5200 under the Lucasfilm Games label. Versions for home computers were not released until 1985, by publisher Epyx. Lucasfilm's next two games were "Koronis Rift" and "The Eidolon". Their first games were only developed by Lucasfilm, and a publisher would distribute the games. Atari published their games for Atari systems, Activision and Epyx would do their computer publishing. "Maniac Mansion" was the first game to be published and developed by Lucasfilm Games.
