I run Ubuntu 16.04 ~/GOG Games/McPixel 3 Demo$ ./start.sh Running McPixel 3 Demo ./demo/mcdemo3: error while loading shared libraries: libSDL2-2.0.so.0: cannot open shared object file: No such file or directory That applies to with the games I buy here. Ofc I could manually fix that but when I buy a game here I expect it to run flawlessy out-of-the-box. Sad...
