Erotic games made the PC-8801 popular, but customers quickly became tired of paying 8800 yen ($85) for such simple games.
Soon, new genres were invented: ASCII's Chaos Angels, a role-playing-based eroge, inspired Dragon Knight by Elf and Rance by Alice Soft.
After a similar game by Tactics, One: Kagayaku Kisetsu e, became a hit in 1998, Visual Art's scouted main creative staff of One to form a new brand under them, which became Key. It contains only about seven brief erotic scenes in a sentimental story the size of a long novel (an all-ages version was also released afterward), but the enthusiasm of the response was unprecedented, and Kanon sold over 300,000 copies.
In 2002 a 13-episode anime series was produced, as well as another 24-episode anime series in 2006.
Early eroge usually had simple stories, some even involving anal, which often led to widespread condemnation from the Japanese media.
