Policenauts is an interactive movie/graphic novel/adventure game with a hard science fiction storyline, written and directed by Hideo Kojima, and published by Konami. It was initially released for the PC-9821 computer platform in 1994, followed by remade versions for the 3DO in 1995, and the PlayStation and Sega Saturn in 1996. The game has never been officially released outside Japan, despite plans for an English localization of the Saturn version. On August 24, 2009 (in honor of the 46th birthday of the game designer, Hideo Kojima), an unofficial English translation patch was released onto the internet. The game is set in a primarily first person perspective and uses a point-and-click interface: the player can move the cursor and have the protagonist (Jonathan Ingram) analyze objects around his environment or talk to other characters in the game. Like in Snatcher, the game features shooting segments where the player must defend their character from incoming enemies. The player can use the shooting trainer at the police department to test their reflex and accuracy. There are numerous puzzles in the game, including an event where the player must dismantle a bomb by following their partner's instructions. The console versions of the game all include support for their respective mouse peripherals. The Saturn version features light gun support for the shooting segments. The game was notable for being an early example of extensive voice recording in video games. It also featured a theme revolving around space exploration and occasional full-motion video cut scenes. The gameplay was largely similar to Snatcher, but with the addition of a point-and-click interface and some first-person shooter segments. Policenauts also introduced summary screens, which act to refresh the player's memory of the plot upon reloading a save, an element Kojima would later use in Metal Gear Solid. The PlayStation version of Policenauts could also read the memory card and give some easter egg dialogues if a save file of Konami's dating sim Tokimeki Memorial is present, a technique Kojima would also later use in Metal Gear Solid.

Prismaticallization is a dating sim, whose hero is a highschool senior named Shoji. He finds a strange object when he's invited to a summer resort by his classmate Akemi. The object causes him to repeat a day, but seems slightly different.

The game is played as an interactive novel, with 2D still pictures of settings and characters being the main graphic elements, and all actions being described via scrolling texts. At several intervals you will have to make a choice that branches the plot in different directions, but that's all the interaction you get to make.

An updated version of Kamaitachi no Yoru with new scenarios, higher resolution graphics, and a flowchart for ease of replaying, among other things.
