Thronebreaker rewards

[Kwanzi]

If you purchase Thronebreaker on another platform (like Steam), do you still get the 20 multiplayer cards, 2 borders, and 2 avatars? Or are they a GOG-exclusive?

Or are they a GOG-exclusive?

They are, because GWENT is only on GOG (and consoles). See this news thread.
