Hello fellow GOG fan! I own 620 games on GOG, and I license 214 games on Steam. Granted some of those Steam games do not have DRM, so consider that an estimate.
Man you sound almost exactly like me lol. A lot of angry persons who have been burned by companies are becoming like us. What sent me over the edge was when Ubisoft threatened to shutdown their legacy activation servers, which would have led to me losing the DLC I purchased for my physical Wii U copy of Splinter Cell Blacklist. They backpedaled after significant fan backlash, but now I’ve been radicalized. I avoid “as a service” to the best of my ability and am deliberately hostile to these corporations.
