Hello,
I searched and found this topic :
http://steamcommunity.com/app/435150/discussions/0/141136086934737420/
In which the user asks if it's possible to play coop between GoG and Steam, and Raze_Larian answers
"Yes (though it looks like that doesn't matter any more)."
What does "it doesn't matter" means ?
Is it possible ? I don't know if all of my friends will buy it on GoG, and I prefer this platform, but want to play with them.
Thanks
