List of Atari, Inc. games
Atari, Inc. was an American video game developer and video game console and home computer development company which operated between 1972 and 1984. During its years of operation, it developed and produced over 350 arcade, console, and computer games for its own systems, and almost 100 ports of games for home computers such as the Commodore 64. Atari began its operations by developing and producing some of the first arcade video games; the first commercial arcade video game, "Computer Space", was released in November 1971 by Atari founders Nolan Bushnell and Ted Dabney in partnership as Syzygy Engineering. The game in part marked the end of the early history of video games and the start of the rise of the commercial video game industry. After its founding in 1972, Atari released "Pong", believed to be the third arcade video game after "Computer Space" and a clone game and the first commercially successful arcade video game machine, and thereafter produced numerous arcade games, including video games and pinball machines.
Asteroids (video game)
A prototype of "Asteroids" was well received by several Atari staff and engineers, who would "wander between labs, passing comment and 
stopping to play as they went". Logg was often asked when he would be leaving by employees eager to play the prototype, so he created a second prototype specifically for staff to play. Atari went to Sacramento, California for testing, setting up prototypes of the game in local arcades to measure its potential success. The company also observed veteran players and younger players during focus group sessions at Atari itself. A group of old players familiar with "Spacewar!" struggled to maintain grip on the thrust button and requested a joystick, whereas younger players accustomed to "Space Invaders" noted they get no break in the game. Logg and other Atari engineers observed proceedings and documented comments in four pages.
"Asteroids" was released for the Atari 2600 and Atari 8-bit family in 1981 and Atari 7800 in 1986. Released in 1981, the 2600 port was the first game to use bank switching, a technique developed by Carl Nielsen's group of engineers that increased available ROM space from 4 KB to 8 KB. Brad Stewart, the programmer tasked to work on the port, used bank switching to complete the game. A port for the Atari 5200, identical to the Atari 8-bit computer version, was in development in 1982, but was not published.
