I thought perhaps such a thread could be of use, like the opposite of the Gameseek thread.
Some AGS games are not added to the database, and may fly under people's radar. If you find something that other people may be interested in, why not post the link in this thread? This could be stuff hidden in plain sight in the
AGS depository on archive.org, or it may be jam games, demos or smaller games that for some reason haven't ended up in the database on this site.
I'll go first: In the Adventure Jam 2021 on GameJolt, you can find the following AGS games not currently in the database:
Nadir is a great and moody short piece set in a submarine.
Long in the Tooth is a short demo with marvelous graphics and animation.
Coffin Valley is a western game.
All Demons must go to Hell is a game announcing itself as user-unfriendly, but it's quite fun to play.
