"Your customers hate DRM," GOG.com's Guillaume Rambourg explained to the assemblage at the London Games Conference. "DRM is making companies feel safe while they handle some business, they are trying to protect their product and protect their sales, but the reality is very different." This is noted on GamesIndustry.biz
(registration required), where they note that while The Witcher 2: Assassins of Kings
sold something around 200,000 units on Steam
, CD Projekt RED's action/RPG sequel sold more DRM-free units on GOG.com than all other digital distributors combined. Here are a few more quotes on the topic:
"The reality is DRM does not protect your content. Every game is pirated within a few hours of release or more often before it's released. DRM is not protecting your product or your sales, it's going to harm your sales in the long run."
"By putting DRM in your games you are working against your consumers, you are harming those you should cherish. It's only hurting your loyal consumers which is counter-productive."
"There is one industry that got everything right - piracy. Piracy quickly understood that digital needs to be simple and easy. That digital consumers are expecting a fast and easy experience. You should treat piracy as competition not as an enemy. If you treat it as an enemy you are blinded and you don't pay attention to what they are doing right."
