By 1987 the PC market was growing so quickly that the formerly business-only computer had become the largest and most important platform for computer game companies. During this time, the improvements introduced with products such as ATI's Radeon R300 and NVidia's GeForce 6 Series have allowed developers to increase the complexity of modern game engines. By 1990 DOS comprised 65% of the computer-game market, with the Amiga at 10%; all other computers, including the Apple Macintosh, were below 10% and declining. By 1990 DOS comprised 65% of the computer-game market, with the Amiga at 10%; all other computers, including the Apple Macintosh, were below 10% and declining. First sold in 1977, Microchess eventually sold over 50,000 copies on cassette tape.
(The game Les Manley 2 satirized this by depicting two beautiful women exhaust the hero in bed, by requesting that he again explain the difference between extended and expanded memory.) Computer Gaming World provided technical assistance to its writers to help install games for review. By 1996, the growing popularity of Microsoft Windows simplified device driver and memory management. From the mid-90s onwards, PC games lost mass-market traction to console games before enjoying a resurgence in the mid-2000s through digital distribution. The uncoordinated nature of the PC game market and its lack of physical media make precisely assessing its size difficult. Electronic Arts reported that customers used computers for games more than one fifth of the time whether or not they purchased them for work at home.
Computer games, however, did not disappear. An early text-adventure, Adventure, was developed for the PDP-11 minicomputer by Will Crowther in 1976, and expanded by Don Woods in 1977. By the 1980s, personal computers had become powerful enough to run games like Adventure, but by this time, graphics were beginning to become an important factor in games. During this time, the improvements introduced with products such as ATI's Radeon R300 and NVidia's GeForce 6 Series have allowed developers to increase the complexity of modern game engines. Increasing adoption of the computer mouse, driven partially by the success of adventure games such as the highly successful King's Quest series, and high resolution bitmap displays allowed the industry to include increasingly high-quality graphical interfaces in new releases. The CD-ROM had much larger storage capacity than floppies, helped reduce software piracy, and was less expensive to produce. First sold in 1977, Microchess eventually sold over 50,000 copies on cassette tape. By 1993 PC games required much more memory than other software, often consuming all of conventional memory, while peripheral device drivers could go into upper memory with DOS memory managers. There's been a much greater falling off of disk sales than anyone anticipated." A third attributed the end of growth in sales of the Commodore 64 to the console, and Trip Hawkins called Nintendo "the last hurrah of the 8-bit world". PC gaming currently tends strongly toward improvements in 3D graphics..
