kokop159: Then isn't Steam easier to update? Just update it and it's done.
stg83: Steam has automatic update which is more convenient but the method for manually updating isn't that difficult as you just have to run the installer and the rest is easy. Also GOG Galaxy will hopefully be functional by the time of The Witcher 3 release next year which will have automatic updating just like Steam. You also get amazing extra content pre-ordering here that is exclusive to GOG that you won't find on Steam like The Witcher Adventure game Closed Beta passes for example.
Well said. Also note that Steam's "auto-updating feature" is very buggy and attempting to disable a game from auto-updating often doesn't work. Why would one wish to choose not to auto-update? For me it is when a patch is released that seems to break more than it fixes, which can be quite common with modern gaming.
GOG can be a little slow getting patches before Steam for some games, which is something I'd love to see change.
The main benefit to GOG over Steam in most cases is that GOG is always DRM free. Meaning once you get the game, the internet and the world can explode, but you'll be happily sitting up in your Earth escape pod playing away in space whilst the rest of civilisation has perished.
