neumi5694: Don't download every new version then in full, but keep one and from then on only the patchers.
This way you waste less space and can stay at one specific version if you decide to.
This is a sensible approach but is undermined by the frustrating way in which GOG doesn't make all patches (let alone installers) available to the user. Therefore the user has to keep checking in on the site to make sure they have the current patch and see when the next patch in line shows up in their library. If the user takes too long, or several patches release in quick succession, they will have to download a new full version of the game since the next patch in line from what they have is already gone.
Example:
User downloads base game, patch 1, comes back in a couple days and downloads patch 2.
User is busy for a month or two unable to game, patches 3-10 release.
User logs in, only to see that the patches available for download are patches 6-10.
User now has to download the base game installer (which is at patch 10), because patch 2 that they have cannot be updated to patch 6 (the oldest now available); it would require having patch 3, 4, 5 first.
Breja: I really don't know why people buy games on release. In this day and age a fresh release is usually still in "early access", just without the label. If you wait a year you'll get an actually finished product, probably with a 20% discount. It's not like there's a shortage of stuff to play.
Seconding this. Devs and pubs cannot be trusted to do the right thing.
