I don't know for sure If I can activate a key but I would guess not. I will instead wait patiently, thanks for the info.
AFAIK if the key is not locked for your country by the publisher it should be activatable on steam despite you not having the ability to buy it in your country. The same problem would arise for me cuz germany is banning what feels like 87% of the whishlist games i wanna play (yes most of em are NSFW)
