D

D is a horror adventure that came out on the 3DO in 1995 and makes clear from the first minute that it wants to be more of an interactive film than a game. Laura Harris enters a hospital where her father committed a massacre without explanation, and instead of hospital corridors finds herself in a gothic mansion full of blood, mirrors, and family secrets. The entire title is told through pre-rendered animations, through which the player moves along fixed paths, and it carries one unusual rule: it runs in a single sitting, with a two-hour time limit and no way to save. Whether the player succeeds or not, it's over after two hours.

This fundamentally changes how D plays. The puzzles aren't especially complex, but the ticking clock turns them into a tense test — and when time runs out, you start over from the beginning. The game relies on pacing, editing, and what it shows only for a moment. Controls are limited to a few directions and interactions, so attention stays on the image. Studio WARP also played with what the player expects: the title hides scenes that most people never see, and several moments that, at release, caused embarrassment even among publishers. The game gives no hint of them anywhere, and some unlock only through very specific player behavior.

Technically, it was an impressive demonstration of what CD media could do — smooth full-screen animation and music that irritates the nerves rather than scaring with a loud jolt. At the time, the game was a hit especially in Japan, where it carried the reputation of an uncompromising auteur project, and in the West it became one of the titles people remember the 3DO for at all. Today it's clear how narrow a corridor it offers players and how little real freedom it contains. Yet it remains an unusually stylish piece: short, tight, unpleasant, and played with a straight face at a time when most similar games snickered at their own B-movie origins.
