These are stand-alone executable packages. They have two personalities: Sometimes they think they're an ELF executable, so you can just run them and play these awesome games, if you have execution credentials (chmod +x [package file]). Sometimes, they think they're an ISO file, so you can also mount them with fuseiso, acetoneiso, or your ISO management application of choice, and peek what's inside.
Inside the packages you'll find two things:
A minimal installation for each game, sometimes next to a minimal Wine installation
A little script (AppRun) to glue it all together when you run the package
- Single file applications
- No installation
- No dependencies (mostly)
Awesome project, if you JUST want to enjoy gaming on Linux then you should seriuosly consider this! :) Simply download and execute the file! Love it! No more compiling, untaring/unzipping, or even "installing" This was long needed for the Linux users who have Mac/windows background. The maintainer/developer is responsive to the queries, suggestions, ideas. I wish more game developers will start using and supporting AppImage
