Christminster

Christminster is a 1995 Inform interactive fiction by Gareth Rees, subtitled "An Interactive Conspiracy." The player arrives at fictional Biblioll College in the university town of Christminster after a cryptic telegram from her brother Malcolm, only to find him missing and the college caught in a quietly sinister academic conspiracy.

Setting

The game evokes Oxbridge in loving detail -- panelled common rooms, locked libraries, porters' lodges, and chapel cloisters. Christminster itself is a barely-disguised composite of Cambridge colleges, drawing on the author's own time at the University of Cambridge.

Gameplay

Built on the Z-machine using Inform, Christminster pairs traditional parser-driven exploration with a strong NPC roster: scholars, servants, and fellows whose schedules and conversations the player must navigate. A built-in HELP system offers hints when puzzles bite.

Reception

Christminster is widely regarded as one of the breakthrough Inform games of the mid-1990s, praised for its prose, its richly populated cast, and its puzzle integration. It helped establish a template for character-driven, literate IF that influenced the next decade of the form.

Distribution

The Mac release packaged the story file with a Z-code interpreter as a standalone application, requiring System 7 and roughly 1.6 MB of free memory. The story file is also playable in any modern Z-machine interpreter.
