AGI Phantasmagoria

AGI Phantasmagoria is a 2000 MS-DOS release whose title points to Sierra's AGI adventure engine, the early parser-driven technology behind the company's mid-1980s games. Projects of this kind from around the turn of the millennium were typically the work of hobbyist adventure-game communities who used reconstructed versions of Sierra's old tools to build new games in a deliberately retro style.

Without firm knowledge of this specific game's content it is more honest to describe its likely context than to invent a plot or mechanics. As an AGI-styled adventure from 2000 it belongs to the small but dedicated fan-adventure scene that kept Sierra's classic formats alive well after the commercial industry had moved on to full multimedia productions.
