vaillantliaison: I have bought 2 games and it's realy work well everething is ok . My only problem is with king bounty legend because a bug inside the game i have read an answer from gog support on topics and i am trying to resolve it with a download file.
Good to hear it's working out for you. You're probably going to have no problems as long as your drivers are up to date and you have all the dependencies installed, like DirectX or the Visual Studio Runtime stuff. But on the rare occasion things don't work Gog's support helps a lot.
Have happy gaming times, mate
