LynetteC: So because l already paid up previously, l don't get a code that I can trade/give away later? (Considering the number of Duke Nukem, Torchlight and Witcher gift codes still floating around.) I also own American Nightmare so I stand to miss out twice! :-(
In past promos GOG did not prevent people from taking extra copies although it isn't clear if they intended for people to do so or not. But as they learned - people were grabbing dozens of codes and selling them elsewhere for profit. That isn't acceptable of course and the only way to really prevent it is to not give away an endless supply of free codes but to limit it to the account of the person wanting the freebie.
They don't owe anyone anything though, and if they decide to give 1 copy of something to one person, they can do that and nobody else is entitled to anything. Kindness and generosity of GOG or any other company should be taken for what it is and whoever benefits should feel happy about that, and whoever doesn't get something should feel good for the people that did and not feel entitled to something free or feel negatively toward the companies in question because they didn't get something too.
Everything is amazing and nobody is happy :)
