// Night Life(1982)

One of Kōei's first video games, Night Life (1982) was the first Japanese commercial erotic game to hit the market, featuring a series of sexually explicit images, and marketed as a tool to help couples enhance their sex life. An intercourse simulator and part of Kōei's Strawberry Porno series, Night Life is considered to be a precursor for the Bishōjo game genre. In-game, the player has a limited set of options, including determining the date of a woman's period, a choice of sex positions and the option of how much time to allocate to each one. The intercourse is then displayed on the screen through the 'Let's Fuck' option, and is non-interactive.
