Games break months after getting them and then their GoG Galaxy stops working. Money spent on games in advance are down the tube, and unless you a buy a game at a time, and finish it within the 30 days you can forget about any refund. So basically games bought is a race to the finish as everything they have is garbage from customer service to games to quality to system to everything.
Biggest scammers in the world, stay away from them and stick to Steam.
