I do not understand why the GOG version is *strongly* recommended for Linux users. Extracting the game files from the GOG version requires either Wine or another external program. The Steam version only requires that you install the game. Also, why do the installation instructions for Fedora not use the COPR repo? The Ubuntu instructions install from the PPA, which is essentially the same. It does not make sense for the Fedora instructions to build from source while the Ubuntu ones don't.
