Gog-galaxy installs this game in the same folder as Call Of Cthulhu 2006. As a result you will get non-working Call Of Cthulhu 2006 and Call Of Cthulhu 2018 :)
This is cool adventure game. But I couldn't play it on modern hardware. This game don't want to scale on 4K-display and don't support bluetooth xbox-one controllers. Controller's arrows work but keys don't, moreover you could not setup it. The setup utility don't recognize any controller keys except arrows.
