The term "eroge" (erotic game) literally defines any erotic game, but has become synonymous with video games depicting the artistic styles of anime and manga. The origins of "eroge" began in the early 1980s, while the computer industry in Japan was struggling to define a computer standard with makers like NEC, Sharp, and Fujitsu competing against one another. The PC98 series, despite lacking in processing power, CD drives and limited graphics, came to dominate the market, with the popularity of "eroge" games contributing to its success.
