Ever 17

Ever 17: The Out of Infinity was released in 2002 as the second entry in the Infinity visual novel series, developed by KID. The narrative centers on a group of individuals trapped in an underwater theme park called LeMU, tasked with surviving for seven days while uncovering the facility's mysteries. It is widely regarded as a seminal work in the genre, specifically for its innovative use of the visual novel medium to deliver a complex, non-linear science fiction plot that relies on the player's perspective shift to reveal the true nature of the events.

The game's intricate structure was largely designed by scenario writer Kotaro Uchikoshi and directed by Takumi Nakazawa. They aimed to subvert player expectations through a meta-narrative that interrogates the nature of digital existence and the role of the observer. Upon its release, it gained a dedicated cult following for its ambitious thematic scope and its effective integration of quantum physics concepts into a character-driven thriller, solidifying its reputation as a benchmark for narrative-heavy interactive fiction.
