I use GOG for years. I believe that when they began to implement their own launcher it was a misstep. I know someone else on their forums pointed it out better than I could but had they stayed DRM FREE without launchers they could have avoided a lot of cost with having to 1) Keep up with the launcher battle 2) Deal with DRM creep coming into their releases 3) Have a unique identity in the game digital distribution world.
The amount of research I have to do before I pull the trigger to buy one of their games made me back up my titles and close my account.
To keep on improving and enjoying life.
