Additional Comments
Digital distribution version from Gamersgate, doesn't contain the Telltale launcher, the game starts up without issues.
Native d3dx9_41.dll is needed to start the game, the file was placed into the game's directory by the installer.
I had to turn off GLSL ('winetricks glsl-disable'). It was the only problem during gameplay, the game is fully playable from the beginning to end.
