Hello guys , i was just wondering, i preorderd the game and this question just came to my mind "how are they gonna send me the stickers posters and art-book when they never asked for my address" and i couldn't find a section neither in "my account" ...so does any one know how this works ?

The preorder on GoG is for the digital version of Cyberpunk 2077.
Everything extra that comes with it is digital as well. No postal address needed.

so i will receive all that at the release i guess ...but i was hoping for some of the things to come in physical form

Only a physical copy of Cyberpunk 2077 also comes with physical extras.
