I installed protontricks and followed the instructions made by others with no luck. Most people seems to be able to start the game without protontricks (only not the videos), but that newer worked for me. So I guess I have some special problem. Steam thinks that the game is running, and some wine processes does run but the game window is not showing up. And I had to hard kill the game with "killall -9 wineserver" (SIGINT didn't work). Maybe it's because I have such a bad and old machine. Anyhow, the game runs flawlessly after I installed steam under wine 5.7, with a 32-bit wineprefix and after I ran "winetricks ffdshow l3codecx winxp directshow". If anyone tries this, start steam with the -no-cef-sandbox option, it won't start otherwise.
