Does GoG have achievements like Steam? If using Steam version for achievements does Steam have to be running? Also I saw on GoG forum that people can't easily play multiplayer without making "direct connections" (whatever that means) so is it easier to play with others if using the Steam version? I plan to mainly play single player but might want to try the multiplayer a little.
Yes. GOG has achievements, GOG Galaxy must be running. I have Witcher 3 on GOG, and there are achievements.
Yes. It's easier to play multiplayer with steam. But, you can play cross steam-gog multiplayer via direct connect with the gog version. The lobby in the gog version is not working, yet.
