46 games in archive from 1984
With the American console market still collapsing — US home video game sales fell to about $800 million — 1984 belonged to home computers and to Japan. Alexey Pajitnov developed Tetris, Elite and Knight Lore redefined what 8-bit computers could do, the Famicom became the world's best-selling home system, and Warner sold Atari's home business.
As the American console business shrank, the most important games of 1984 appeared on home computers. Ultimate Play the Game's Knight Lore introduced its isometric Filmation engine on the ZX Spectrum in December; Boulder Dash inspired enough imitators to found the rocks-and-diamonds genre; Epyx released Impossible Mission on the Commodore 64; Broderbund released Jordan Mechner's Karateka; and Sierra released King's Quest for the IBM PCjr. In Britain, Jet Set Willy was the top-selling home computer game of the year.
1984 was a year of consolidation. Atari was split in two, Mattel sold its video game business, including the Intellivision, to the group that became INTV Corporation, and Hasbro bought Milton Bradley. In Japan, Sega merged with CSK to form Sega Enterprises. The arcade was quieter but still inventive: Nintendo released Punch-Out!!, Data East released Karate Champ, which laid groundwork for one-on-one fighting games, and Atari Games ended the year with Marble Madness.
