Night life

The first commercial Japanese erotic game, Night Life is a simple simulation of sexual intercourse, marketed as a tool aiming to help couples enjoy their sexual life more. Player interaction is restricted to a few choices. The player is given the option to make a schedule to determine the date of the woman's period. By answering a few questions, the player can choose a set of sexual positions he is willing to use for the virtual intercourse (these positions are also available as a "demo", accessed from the game's main menu). Afterwards, the player chooses the amount of time for each position. The subsequent display of the intercourse (dubbed Let's Fuck!!) is non-interactive and consists of a small picture of the chosen position in the middle of a screen, accompanied by a timer.
