Unless keys that allow access to multiplayer are provided it is false advertising and deceptive, which would be uncharacteristic for GOG.
Multiplayer is not only a part of the game, it is also an advertised part of the game, so expecting the keys to be provided is hardly surprising. Grogger: Valid keys are required for joining multiplayer games, it does not matter if some consider it 'completely boring' such opinions are useless and irrelevant.
