In which I play the earliest adventure game explicitly based on Sherlock Holmes, giving the history of both who wrote the game and how it got written. It was coded based on an unusual system where you can edit from within the game. bluerenga.blog/2026/08/01/s...

Sherlock Holmes & the Case of the Elementary Rescue (1983)

People are going to buy these things and then after six weeks or so they’re going to put them up on a shelf in their closet and ignore them … we saw that there was a need for something …

Dr. Lauren Liebe talking about students learning how to play PLATO games. The early graphics are so abstract by today's standards that they couldn't even tell what they were looking at

A screenshot of the PLATO game Camelot, demonstrating the "graphical uncertainty" witj the game's first-person perspective.

in which I play the odd graphical adventure game Adventuremania for TI-99, including comparisons between the author Martin Webb and child movie stars (and how teenaged computer entrepreneurs in general dealt with their parents in the early 80s) bluerenga.blog/2026/07/27/a...

Adventuremania (1983)

As a child I was obsessed with making stuff, it started with cardboard boxes and moved on to wood by the age of 5. By 10 I was constantly visiting rubbish dumps to find broken electrical stuff I co…

the conclusion to Peter Kirsch's 16th game, with both clever preparation puzzles and some of the worst parser abuse I've seen from the author; also, some brief introspection as this is the last of the official 20-game Adventure Game of the Month series bluerenga.blog/2026/07/25/d...

Danger Is My Business: Stinkerus Americanus

I’ve finished the game; this is continued from my previous post. Just to get it out of the way first, we’ve got headhunters again, something I’ve written about before. Since this …

All the Adventures returns to Australia. I play two games made by a teenager using his friend's adventure system for VIC-20; they come out better than you'd expect by using the "fan fiction shortcut" of supernatural creatures having common lore. bluerenga.blog/2026/07/18/d...

Deathship / Werewolf (1983)

It was remembered as a “joke” computer, with its 22 by 23 character screen and 3.5Kb of RAM. Revisionists forgot that at the time there was nothing else, and that within the confines of…

Last weekend, one of the most important British text adventures was preserved in its original form (Commodore PET!) for the first time. In this post, I examine the circumstances of its rescue and some other details in the starting sections. bluerenga.blog/2026/07/11/c...

Catacombs: The Rescued (Previously Presumed Lost) 1981 Version

(Continued from my previous posts on Catacombs, which you probably should read before this one if you want the full background.) Last weekend, I received a message from Marcel Ingram Lansing that o…

Last time I introduced Thissala, an adventure game from 1979 that was lost since last year and seems to be one of the largest ever made. Today's post I start exploring in earnest for the first time, finding where it overlaps both Adventure and Zork. bluerenga.blog/2026/06/16/t...

Thissala: Dense in Timothy and Flora Unlike Any Other

(Continued from my last post.) As is tradition with one of these gigantic cave-delving based games — and there is cave-delving, even though it wasn’t clear at first — let’s …

Thissala (potentially) is one of the largest adventure games ever made, started in 1979. It was not only lost but unknown to even exist until last year when it was unearthed off an old Data General drive. bluerenga.blog/2026/06/14/t...

Thissala (1979)

Public attention, as well as the attention of groups such as this, has been focused on the design and application of large, expensive “super computers.” Our national preoccupation with …

My finale of The Coveted Mirror, including discussion of how being oriented towards non-violence and for children led to some particular innovations. Also, the unexpected connection with the modern EA Sports empire. bluerenga.blog/2026/06/12/t...

The Coveted Mirror: A Rosy Future for All of Us

I’ve finished the game, and my previous posts are needed for context. To continue directly with the most immediately clear solve: the way the barrel works is as a teleporter. It’s not a…
