blotunga: And to be clear, even GOG isn't 100% DRM Free, but it's as close as it gets. True DRM free would be the ability to sell/give away your copy after being done with it. But of course that is one of the major reasons for DRM, not pirates.
ejiki: I don't agree... DRM is just technical methods to control license fulfillment. GOG Games have a license and not have DRM, they a DRM-free, but neither free nor open software.
I disagree here. GOG games are mostly DRM-free, but not completely. We still have games with instruction manual look-ups and some games where you need to ask for a serial number to be 100% functional (Neverwinter Nights comes to mind).
Although GOG provides everything to satisfy the DRM requirements, they are still necessary. If GOG went down today and you lost your NWN s/n, you could not play multiplayer. Or if GOG went down and you lost your manual, you could not play a few games with the instruction manual check.
Not super-strong DRM (and even admittedly NWN's DRM is formed from the basics of how multiplayer data is relayed, so it's purpose wasn't just DRM, it had a dual-purpose). But still a little sprinkling of DRM.
