"Steam is winning with its ease of use," he says. "In that regard, I think much can be done in GOG without losing its core values and the way it operates in general."
Yeah, not really. Ease of use is part of it but I would argue GoG is equally easy. Steam also has a breadth of features for users.
More importantly, as it pertains to GoG, Steam allows DRM.
This is a fundamental problem for GoG. Publishers want DRM. Consumers largely don't care. For that reason, Steam has a much larger library, especially for big AAA titles. Every game that's on GoG is also on Steam. They'll always be the little guy catering to a niche market of consumers who demand DRM-free games. Get rid of that and we can start talking about ease of use and features.
Obviously, that's not what I want, but if they want to compete with Steam, it's what they'll have to do.
