Goatbrush: When you consider pre-Steam gaming you also have to remember that the games were for the most part down to the choice of the user as to which patch they wanted to play at, which is all most of the people voicing concerns want to be able to do. If Steam is going to force the latest patch on players without a rollback option, then I don't think it's unreasonable for them to actually test that the patch is safe and functional before application.
Yeah, sorry, but I don't buy into that "forcing to patch" BS I hear in regards to Steam so often.
In the twenty years of PC gaming I always used the newest patch available. Apart from the fact that you can't "cherry pick" patches and always only avoid the newest one, there simply was never an instance were I didn't want to patch a game.
And GOG is also forcing you the newest patch when they update their installers. Sure, you might have the old installer backed up, but not many do this.
