On the CRT, a pixelated photograph of a real woman’s face. Coarse resolution, a reduced palette, the banding of JPEG compression, and yet unmistakably the texture of “not a drawn picture.” The cooling fan starts as the CD-ROM spins up; an icon blinks for a few seconds with every choice. In the window of a text adventure, material that is neither a 2D character nor full video, sitting between photograph and footage, advances the story across a narrow band of expression.

Overview

Live-action eroge (実写エロゲ, jissha eroge) is the umbrella term for adult computer games using filmed footage or photographs as material. This article centres on the live-action-capture adult games of the 1990s PC-98, Windows, and MS-DOS environments, covering their technical conditions, representative forms, and decline.

Live-action eroge use photographs or video, rather than 2D-CG or pixel art, for their graphic material. Most take an adventure or branching-choice format, combining text-driven scenario with the display of live-action images. Concentrated in the early-to-mid 1990s, they formed a temporary boom with the spread of the CD-ROM drive, then fell from the mainstream under the rise of CG technique and the doujin 2D-art culture. Technically the CD-ROM medium was the decisive precondition: a floppy disk (1.44MB) could not hold filmed images in quantity, and only with the CD-ROM (about 650MB) standardising in the early 1990s did it become possible to embed dozens to hundreds of live-action assets in one game.

Technical features

PC-98-era live-action eroge ran at 640x400 resolution with a 16-colour palette. Displaying photographs there required colour reduction, dithering, and palette optimisation, producing a distinctive “coarse live-action” look later reappraised as an aesthetic by retro-game enthusiasts. After the move to Windows, full colour and JPEG compression allowed higher-quality assets, and each work’s technical character was shaped by balancing photo count against image quality within the CD-ROM’s capacity limit.

Works using video adopted QuickTime, MPEG, or AVI. CPU limits made short, low-resolution, low-frame-rate clips the norm, inserted in fragments; full-screen high-quality playback remained difficult until the late 1990s. Video-heavy works inevitably grew large and tended to ship as multi-disc productions. Live-action eroge were also one category of the wider “live-action capture game”: capture was tried across arcade, console, and PC from the early 1990s, with non-adult works such as Digital Pictures’ Night Trap (Sega CD, 1992) appearing in the same period. Live-action eroge developed as the adult branch of this broad technical current.

Narrative forms

The mainstream form combined a text-based adventure with live-action images: the player branches the story through choices, with different live-action scenes at each branch, progressing in first person through conversation, relationship development, and sexual scenes with a heroine. It shares the structure of the novel game while using live-action material for standing portraits and background CG. A simulation form also existed, managing the heroine relationship through parameters (affection, stamina, morale) that branched the ending, with live-action material inserted at each event. A completion or photo-album form had thin narrative, unlocking the heroine’s photographs by clearing mini-games or finding hidden images, functioning effectively as a digital photo collection.

The decline

Live-action eroge contracted from the late 1990s for several converging reasons. The first was the convergence of the mainstream bishoujo game onto 2D illustration through advancing 2D-CG technique and doujin culture: Leaf’s Shizuku and Kizuato (1996-1997), To Heart (1997), and Key’s Kanon (1999), 2D-centred novel games, produced hit after hit and shifted the market toward 2D characters. Added to this was the difficulty of managing performers: securing models or actresses required shooting and appearance fees often higher than 2D-CG costs, making entry hard at the doujin level and keeping the base narrow. Viewer taste also changed: those seeking live-action material moved from the late 1990s to AV, adult photo magazines, and later internet video, and demand for live-action in game form shrank.

Present position

Post-2000s live-action eroge fell from the market centre but continued in specific niches (mature-woman, cosplay, particular-model exclusive works), with some Windows titles and new releases still appearing from a few makers, though the overall scale is small. Among retro-game enthusiasts and PC-98 emulator users, 1990s live-action eroge are reappraised as “documents of their time”; the distinctive aesthetic that formed under the constraints of resolution, palette, and storage medium is referenced as an expression with a sensibility apart from present-day full-HD and 4K.
