As for backup, I do them regularly, so yeah.
Good. Now go do a backup of a backup (a mirror preferably) ;)
Not joking. Any backup can become useless any time for stupid reasons. With currently available media it's only a matter of how long till that happens (I'm assuming you don't employ magnetic tapes nor experimental currently-BS-price-point storage facilitators).
Also, protip, and this is really important, ALWAYS run checksums on files when backing them up AND include checksums' files on same backup media, for detecting file breakage (even a bit flip can happen from unfortunate placement of neutrino route, no joke).
You can only get fed up so much before you reach a point where you cannot take it any longer.
GOG is falling to shit.
I advice you to reevaluate your presence strategies on this platform as well as take care of offline installers' purchases full backup asap.
Yeah I know. It's just that as things stand, GOG is still the "best" place when it comes to drm-free and offline installers, especially if we consider updated builds (while we do get the 2nd citizen treatment on some releases, it's not as bad as on other platform less known/used than GOG).
Yeah, I don't know, maybe if you care about broad catalouge then MAYBE GOG is ok-ish.
It's standards are actively decaying and this is THE TIME to pull out.
There is also Playism (but they offer close to nothing but japanese indie games, since that's what the platform was created for).
GOG is really stepping on thin ice here constantly pretending nobody sees this.
What are they trying to become - new HumbleBundle? (TLDR, HumbleBundle TOS quite literally violates EU law and they already blocked access for MANY people just because they were reselling or even just merely activating their legally obtained there keys on not-their-primary Steam accounts, both of which are legal in EU, and so it cannot be prohibited by any form of TOS, furthermore any platform restricting access to all purchased content for such customer is literally engaging in illegal act, and it's only a matter of time before the platform gets group sued to oblivion)
edit: fixed some formatting issue
I'm not sure anymore if GOG is either outright ignoring these issues hoping for them to fade away, think of us as just a minority, or if they are thinking on something else too.
It is still leaving a bad taste in my mouth no less.
It's funny how sometimes we conduct in-between thread conversations and sometimes I catch myself posting a response in one only to see your relevant question elsewhere few minutes later :P
For the sake of deduplication I'm just going to link what I said just now: https://www.gog.com/forum/general/boycotting_gog_2021/post827
(tho you might have already seen it judging by your new post made when I was composing THIS one :D)
