Hi,
I bought this game years a go on kickstarter (BARON (special edition) ). I have all that stuff e.g. poster, CDs & Steam key: Is it possible to get the game on GOG without buying it again?
I already wrote to warhouse support, but nobody replied.
Cheers, Michael

And what about this:
https://forum.kingdomcomerpg.com/t/game-is-on-gog-have-not-redeemed-steam-code/51504
?

The studio replied. This issue is sorted.

Could you tell us what studio replied about the issue? In my case they reply unambiguously "No", even if I did not activate my backer reward (Baron digital) in Steam. Only for "special and very limited cases" they said. Don't know how they decide is case special or not, but I saw a message from a Knight backer (lower tier than Baron) on their community forum about successful redeeming of GOG key given to him by WH Studios support team instead of Steam reward.

Just saw this as I was planning to start the game now that bugs seem more or less fixed.
Well, this is a disappointment. What the hell is the problem anyway ?
I mean the game is already on GOG, what can't they just give you the choice of a key for Steam OR gog ?

It probably has to do with the fact that it came out on GOG 15 days after Steam.

Guess I'll activate it on Steam (sad panda).
