Standard tarball packages; tar.gz
Unix deserve a standard. What ever happened to neutral tarball unix packages?

Unix also deserves experimenting, innovating, and not being stuck doing the same stuff again and again since the eighties.
AppImages are standard, neutral ISO files with standard, neutral ELF headers, and the whole point of this project is to provide the ease of use tarballs can’t provide for a set of use cases: being able to play with a single file and a single click, without unpacking.
For the rest of the users, most of these games are already available in tarballs anyway on their respective websites, and AppImages can also be unpacked with standard tools like `mount`, `fuseiso` or `7z`, following the instructions on https://github.com/RazZziel/PortableLinuxGames/wiki/Starting-off#taking-it-apart
While I value your input, I hope you understand why I must respectfully decline the petition, as it’s contrary to the main objectives of this project :)
