Night Life (video game)
Night Life (ナイトライフ) is an erotic simulation game by Kōei, released for the PC-8801 computer in April 1982. It was one of the earliest commercial Japanese erotic computer games, featuring sexually explicit images, and a precursor to the modern eroge genre. "Night Life" was marketed as an aid for the sex life of couples. It included such features as a schedule to determine a woman's period, and a catalog of possible sexual positions, with artwork consisting of black-and-white outlines.
