All the Adventures aims to give the history about and play every adventure game ever made in chronological order. The 1982 sequence has just concluded, and I've written a post looking back and collecting some notable games.

It’s been a while since I’ve gotten to do one of these; my 1981 in review was posted December 20, 2021. The chart with plot types like Rescue, Escape, etc. just isn’t that helpful…

My conclusion to the grand cinematic experiment for PC-88 from XTAL SOFT in Japan, Cosmo Cross. I get past the adventure section and reach a mysterious planet full of monoliths, and a cutscene which aspires for an era far past its time.

feel free to drop thoughts in the comments! I've still been poking at PRISM every few days because it feels like there's still more there I'm missing, even if jumping to the final solution is impossible because of broken puzzle reasons

All the Adventures dips back to 1982 for a space sim-adventure game hybrid from Japan. I give the history of how a music company switched to games and the workings behind the space-combat section:

Alas: I needed to do at least one more post on PRISM (the real life treasure hunt from 1982), as there's a version I didn't know about for Atari computers. The images are different enough to cause some of the potential clues to radically change.

Here's my last post on PRISM (for now), the Apple II game with clues to find real-life treasure. I work out how the game is likely hinting how to find a burial spot and I find an unexpected clue in the game's background sounds.

The study of PRISM continues, as I go back over some history of Masquerade (which the game was heavily inspired by) and try to get at the central question of: how do you specify the exact location of three different buried treasures with 1982 technology?

plus

The treasure has never been located, so today, All the Adventures embarks on solving the mystery.
