I have seen a number of projects made with Adventure Game Studio which do not offer Linux build, even though the engine does, so I will outline a very simple method of running any AGS game on Linux natively. I have yet to find even a single title that doesn't work flawlessly following these steps:
- Go to the Releases section of an AGS Github page and download the latest version (at the top), by looking for a file named ags_[version_number]_linux.tar.gz under Assets below the changelog.
- After downloading the archive, unpack it and you will be presented with one folder named data and two files, README and startgame bash script.
- Place all of your game files in the data directory, then run the startgame script in the main AGS folder and enjoy!
Repeat steps 2-3 for any game you wish to play in this way, which is to say do not put several games' files in the sama data dir, rather unpack AGS in a separate location you will you use for that title only.
