GOG is a company that provides communication services, PC Game development and digital movie development company, founded in 2008, headquartered in Poland Warsaw, mainly dedicated to single-player games and digital movie sales services, many old games are used for network sales at very low prices.

It is worth mentioning that many games are based on the DRM model for sales. DRM is the acronym for Digital Right Management, which is a real-time online anti-piracy system that many game publishers and software vendors, including Ubisoft, are using. users need to stay connected in the game or software and pass the DRM test in order to get a genuine license.

GOG North America president said in an interview. The fact is, DRM technology, no matter how much it develops, can not change the status quo of games being cracked one by one, and GOG said this based on the existence of DRM or not, will not affect the pirate players, but the real impact is those genuine purchasers.

He also said, "Single-player games that require online activation are really not a good way for publishers to treat customers who just paid $59 for your game?" Indeed, DRM technology doesn't protect any product, and in the long run, it hurts your fans and your brand.

The GOG Galaxy platform from GOG is a DRM-free gaming platform and replicates some of the features found in Steam, such as automatic game updates, social chat and an achievement system.
