In the list of Supported software are FEAR, FEAR2 and the three STALKER games, together with installation scripts. I am a complete newcomer to PlayOnLinux, but as far as I can tell the scripts are for the STEAM versions of the games. I have the GOG versions, with their own installers. How should I change the scripts to allow this ? Is it indeed possible to change the scripts or will new ones have to be written?
