Of course exceptions may happens. In this particular case, however, it seems like OP wants to get rid of some unneeded titles from his library and demands money back. Nothing comes free, someone does his job, got paid and now has to give money back because OP changed his mind. I believe people should learn taking responsibility for their actions (sometimes in a hard way), otherwise we are all doomed..

I found it in the terms, basically sales are considered final after 30 days, so any time after that point it wouldn't be returnable.

Which makes sense, GOG isn't going to wait years in order to spend the money in case people want refunds.

Officially, it's 30 days no matter what. However, they have the option to offer discounts beyond that period at their discretion (and are much more likely to do so if the product hasn't yet been downloaded), as long the customer requesting the refund is in good standing.
The 30-day timer does stop the moment they receive a support/refund request, though.

Honestly I've never checked that part : )
I've never claimed money back for digital goods and not going to. As I said, 30 days is more than enough to fix any mistakes.

I haven't used it either. I've been pretty lucky over the years. But, the games that I would like to have been able to return were all prior to the new policy. IIRC, it was i76 and Blood 2 were more or less impossible to run on my rig a the time due to a bug. But, that was some time ago and I think my hardware is different.

Personally I assume if the game was tested and works for the support, the problem lies on my side ; )
Usually everything works out of the box. I think I had problem with Gangsters: Organized Crime only, can't remeber how i fixed the issue with colors but afterwards worked flawlessly.

Well, I am speaking for myself only. It just happens I know a few tricks and wouldn't bother support if something doesn't work. On the other hand, my OS was always heavily stripped down with some unusual replacements, would be a living hell for any support to figure out where the problem lies ; )
From my perspective games here are working surprisingly well, no flies on The G-Team I'd say. Of course it's not likely to test any software on every possible configuration, problems happens from time to time. Right now I'm about to finish Fallout 3, didn't experience any issues till now. On the last mission the game crashed several times. But again, OS is not a pure ms windows and the same with sound and graphic drivers. Not to mention mods I have installed..
Just like you've mentioned, GOG is very generous with their return policy. I wouldn't bend their trust.

Two things

1) Countries absolutely can require companies to abide by their laws even if they aren't resident there, if they want to sell in those countries. New Zealand is far smaller than Aus yet we have GST levied on certain online purchases now- from companies over a certain size of sales; Steam definitely does, not sure if GOG has enough sales to have to- and the vendor has to administer, collect and pay it.

2) SnappyD is 100% misrepresenting Australia's consumer law. There's no unlimited absolute right to a refund under any and all circumstances such as simple change of mind, just a fairly standard 'remedy, repair or refund' situation and limited, situation dependent, change of mind. Problem with steam was that they refused to do anything at all, GOG allows all the 3 Rs and an exchange (on request and so long as you don't take the piss).

Asking for a refund after 2 years when there is no known problem is unreasonable and would not pass muster if a complaint were made, software does deprecate and has an end of life and that is acknowledged; there's as little right to perpetual support for it as there is for a washing machine or toaster. You couldn't take your unopened copy of Office '95 back to a retailer and get your money back for example, nor could you take an unopened retail copy of Witcher 1 back and expect a no questions refund for 70AUD ten years later- but you might be luckier with Far Cry 5. ACCC will not protect you from being an idiot and buying stuff you don't use (and I say that having many, many games I haven't played myself), only from corporate malpractice.

So if it turns out GOG doesn't abide by Australia's refund laws, are you going to sue GOG? Will you hunt them to the four corners of the earth? Will you curse them with your dying breath? Will you become apehater 2.0 and spam the forums with "GOG DOESNT HONOR REFUND REQUESTS GOG SUX"

This might be a bad time to tell you this, but the earth is an oblate ellipsoid.

Wow Poland is poor af lol

Well, at least we can play all the games without any censorship ; p

Umm,I got news for you and it's bad.I can play any game that has been (not censored) and I'm sure there is a lot that can.
Ah shi*,I stuffed it.What I meant was any game that is uncensored.

And I meant, we have no censorship whatsoever and several other things, you wouldn't even dream of ; )
I do travel a bit and I know what I'm saying.
