MarkoH01: GOG always included serial keys in a seperate menu.
Of course they do. The point is that in case of The Vanishing of Ethan Carter it is
not a serial key, but a code for an extra which is bundled with the game. They also do not give you a code e.g. for the additional CD version of Star Wars Tie Fighter or the additional SVGA version of LSL 6, because it does not make sense to have to redeem a code to download a game extra.
MarkoH01: It's the same with the Baldur's Gate keys.
Baldur's Gate is something different because the code is for another
product which has been on sale separately. As far as I remember the Redux version of The Vanishing of Ethan Carter never has been on sale separately, so nobody already could own it.
finkleroy: Maybe it's so people who can handle running the UE3 version but not the UE4 version can gift the UE4 (Redux) version.
With the same reasoning you could lock every extra behind a separate code. Someone who does not like the sound track could want to gift it to someone else, someone who has no use for a wallpaper..., someone who has no Mac could want to gift the Mac OS version and someone who does not speak some of the game languages could want to gift those language versions to someone else. :P
finkleroy: It would have been nice to have been informed of this when I purchased the game. If they did, they didn't do a very good job of explaining how it works.
That would have been the least, to clearly announce the code to redeem with the purchase or when it has been added to the game.
