Simulation 69

Simulation 69 is a 3D visual novel for players who like校园-set harem stories with a mix of humor and mystery. It plays lighter than most drama-heavy entries in the genre while still leaning into its adult themes.

Story

The protagonist lives a quiet life with three women while recovering from a difficult past, but worsening headaches and strange, glitch-like distortions in the world around him suggest something is deeply wrong. As he prepares to return to college, he starts digging into the source of these disturbances while dealing with the people around him.

Gameplay

Players guide the protagonist through his return to college life, making choices that shape his personality and the path he takes with the women in his life. The game combines dating-sim style relationship choices with narrative investigation, as small oddities and glitches hint at a larger mystery to piece together over time.

Features

• Animated 3D scenes with a distinct visual style
• Multiple relationship paths shaped by player choice
• A mystery thread woven into everyday school and home life
• Humor-driven tone alongside heavier BDSM and group content
