Night Life

Night Life (ナイトライフ) is an erotic simulation game that is part of Koei's adult label, Strawberry Porno series. The game was touted as an educational tool by the company to help couples enhance their sex life with one another.

Like the rest of the Strawberry Porno series, Koei will deny making this game as any adult game is not listed in its company history. Koei has distanced itself from the adult entertainment industry in the early 1990s and seeks to retain its current public image. Kou Shibusawa nervously chuckled when asked about these games in 2008 and remarked, "Gotta try everything in life once", before dropping the topic.

Gameplay
Players are given a limited set of options to tinker with before initiating the virtual intercourse phase of the game. These options range from determining the date of a woman's period (thus serving as a rhythm method calculator) to deciding on which sexual positions to include and how much time should be allotted for each one.

The resulting sexual intercourse is then displayed on the screen with a timer via "Let's Fuck!!" option which outlines the graphics in white. A sex diary option is also available for players to record their gameplay experiences.
