List of best-selling video games for older computers

Older computers
This section lists the sales of video games released for older personal computer platforms such as the Amiga, Apple II, Atari 8-bit and Atari ST; BBC Micro, Commodore VIC-20 and Commodore 64; FM-7 and FM Towns; MSX, NEC PC-88 and PC-98; and the Sharp X1 and X68000. The computer game industry was much smaller when these platforms were active, but gradually increasing; the best-selling computer game up until June 1982 sold 35,000 copies, a major hit in 1983 would have sold around 50,000 copies, and a major hit in 1985 would have sold around 150,000 copies. As such, the threshold is at least 35,000 sales for titles released up until 1982, 50,000 for titles released in 1983, and at least 100,000 sales for titles released from 1984 onwards.
