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.
In the early nineties the atmosphere in Japan became more and more hostile towards bishōjo games.
In 1989 serial killer Tsutomu Miyazaki was arrested and was revealed to be a consumer of lolicon manga, causing widespread opposition to pornographic manga, otaku and anything similar.
Throughout the nineties, bishōjo games underwent an evolution from being one of the most technologically demanding types of games (because their detailed 2D graphics required a large amount of storage space by the standards of early computers) to one of the least (they rarely use 3D graphics).
Thus, more than regular games, the main employees required by bishōjo game companies today are not programmers but artists and writers.
Prior to 1985, girls were generally drawn either as normally proportioned adults or super deformed children.
