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...
The Coveted Mirror continues, as I finally locate the long-sought-after witch, who needs the shadow of a child. bluerenga.blog/2026/06/10/t...

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...
All the Adventures continues with the Apple II game The Coveted Mirror, a game with a confusing plot and far more emphasis on graphics than most entries for the Project. bluerenga.blog/2026/06/01/t...
The Coveted Mirror for Apple II continues, where I win at inexplicable jousting and fishing, have a conversation with a dog and a horse, and contemplate faking a designer label. bluerenga.blog/2026/06/06/t...
The Coveted Mirror continues, where I explore the extensive map, and explain why it feels like a proto-version of later Sierra games (despite not being Sierra-affiliated) bluerenga.blog/2026/06/03/t...
The 1982 text adventure game Epic Hero 3 continues, where I experiment with capabilities while shifted into an alien form. bluerenga.blog/2026/05/29/e...
The conclusion to Epic Hero 3, involving more experiments with technology, a curious vibrating triangle, and an ending with secret undertones (at least the way I played it). bluerenga.blog/2026/05/31/e...

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...

Epic Hero 3 continues, as I manage to blow myself up, communicate with aliens, and use a biological transformation chamber (which is just as neat as it sounds). bluerenga.blog/2026/05/24/e...

(Continued from my previous posts about the game.) Progress, but not quite as much as I’d like. Still, I think I’m one or two posts away from the end. The most immediate thing I solved …

(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: Dense in Timothy and Flora Unlike Any Other
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 …

(Continued from my previous posts on the game.) I was trying to push to the end, but I still must be missing something fundamental. At the least, I can say (checking the list of rooms in the machin…
Epic Hero #3, Venus Must Live: Xenoshifting
I’ve finished the game, and you’ll need to have read my previous three posts to understand this one. Last time I was thinking about the bug I had run across with the rod becoming two ro…
