Thus free from controversy and fueled by continuing improvement in technology, in the 1990s the bishōjo game industry underwent a decade-long boom.
The first major title of the 1990s was Tokimeki Memorial.
The first bishōjo games were not too popular, At the beginning of the genre almost all the games were pornographic.
A notable landmark was Jast's Tenshitachi no gogo (1985), a precursor to the modern dating simulation.
Bishōjo games are similar to Choose Your Own Adventure books in the way of narrative, in which the game tells a story but the player may make choices to change how the story flows. Bishōjo games began to appear in Japan in the beginning days of personal computers.
Since the late nineties, there has been a trend towards better storytelling in mainstream bishōjo games.

This organization tamed down the most objectionable content in the "wild west" of the 1980s.
Both were first released on the PC with erotic scenes, which were subsequently removed in their console ports.
The bishojo gaming industry has resisted the transition into 3D graphics because of the blocky and distorted nature when viewed zoomed up close.
