Truth007: You should back up your games immediately after purchase, I never understood why people don't.
Indeed. This isn't the first "Bait & Switch" GOG have done either. GOG removed the original .exe's to several DOS games (taking away the option of running DOS games under DOSBox) simply because they also ran under ScummVM.
delicieuxz: Because backing up hundreds, or even thousands of games, some of which are 50+ GB in size, isn't feasible for many people. And if you want your backups to be safe, you should have at least 2 copies of your backups, and store them in different places. That's costly for an individual, and sometimes people don't even have another place they can store a redundant backup in.
It's understandable not everyone backs up everything due to capacity, but 15MB games like this are fairly small. Much smaller than the typical size of personal data everyone should generally get into the habit of backing up as well ("the cloud" may form one layer of backup, but "the cloud" is not a backup by itself).
delicieuxz: A part of the service that GoG provides is backup of people's games for them, while making the previous versions available.
Unfortunately they don't make previous versions available anymore for offline installers. See the issues with Divinity Original Sin where the newest version has an unfixed bug and yet GOG repeatedly refuse to provide people with an older bug-free version. This is exactly why post-Galaxy GOG is really not a "backup" anymore...
delicieuxz: And if GoG every shut-down for any reason in the future (and I hope that doesn't happen), there would be an announcement of it which could then inform people that they need to download all the offline installers for their games. And the offline installers for all distinct presentations of their games should be available for them to do so at such a time.
That's a lot of if's. If GOG ever shut down, they won't put in any effort for alternative presentations precisely because they'd be shutting down. And if they announced they'd be shutting down in 30 days time, and everyone suddenly tried to re-download everything, I doubt people would even get 20% of their catalogue downloaded due to massively overloading the server. See
previous examples of Steam outages on Christmas Day caused by one single game, then multiply by days / weeks due to hundreds / thousands of games. Last minute "panic grabs" are not a wise backup policy at all.
