No, he already knew or should have known it had no "anchovies" when he paid for it. He is not entitled to the value of some other bargain, because he never made a bargain for anything other than what he purchased.

Honesty is the best policy when running a service based business like GOG, informing Oceanic users that they would be purchasing a censored version on the main store page based on their profile settings would completely prevent an issue like this from happening, instead most companies would rather prefer to "sweep things under the rugs" as one would say.
Witcher 2 from what most can assume, is a product of extremely high pedigree and such honesty to potential customers would not impact sales negatively at all, in fact, it would create a greater sense of trust between the company and the general consumer, which as we all know is extremely important when running a business.
As a customer from New Zealand, how could he have known about the censorship if he pre-purchased on the 10th? There was nothing on the GOG site or forums that would indicate that New Zealand would be receiving the censored edition, only after the credit purchase was accepted did he find out that the version had the (AU) tag next to the name.

No honest business is in the business of trapping people into buying something they thought was something else. It doesn't matter if he should have known or not, the fact is he didn't know and so should be refunded for purchasing something other than what he thought it was. There is no disputing the menu changed in the last few days when Australia censored the game and Namco Bandai decided, without any announcement, to also give NZ customer the censored version (presumably to make distribution easier for them).

It's simple really and refunds are in order for anyone who isn't with full knowledge and intent purchasing the censored version.

Edit: It's not like GOG are going to miss out really because I'm certain all those refunds will go back into purchases as those individuals find other resourceful ways of getting the uncensored version.

@johannes1212 / mezla1058
Are there ANY indication from the GOG site that they'll be receiving the AU/CENSORED version BEFORE the purchase?

IF NO, then yes mezla1058 deserves a refund because he received what he did not ordered. But IF it was CLEARLY stated then it's mezla1058 own fault.

@mezla1058
so you decided for a refund even they will give you your anchovies later?

Baloney. He never made a contract to buy an uncensored version of the game, and the knowledge that New Zealand would get the censored version was everywhere, days before GOG began accepting payment.

As I said many times before AU tag didn't appear next to the name of the game until the CC transaction went through.

No indication whatsoever, in fact I screencapped a few pages from the 10th of may after i purchased it just to make sure my complaint was legitimate, which it is. In fact it still is as the product page for AU/NZ users still doesn't indicate the censorship or version differences.

johannes1212 / mezla1058
BUT in the first place during PRE-ORDER.. did they mentioned you be GETTING the uncensored version?

negative
No he didn't but the issue lies with the fact that CDPR and GOG are treating both versions of the game (AU and uncensored) versions as the same, hence the lack of need for a specialized contract agreement for both, when in reality they're 2 different products (see other similar cases with censored products, their contracts would differ depending on country versions/censorship).

As to your second point, the average customer should not be made to scour the forums and blog sites online just to make the most basic of purchase decisions, they should be fully informed of whatever they wish to purchase ON THE PAGE of where the product is hosted on. Business customer relations 101.

@mezla1058, I too sent a rather abrupt and dissatisfied sounding email to GOG support asking for a solution to my unwitting purchase of the censored NZ version of TW2. They advised me that they would change my version should it become possible for them to do so. My initial anger over issue has faded, GOG have, as others mentioned done all they can to make sure we are satisfied and in the end we can mod our versions to be exactly as we want them.

I agree, I'm much less fumed over the whole issue now as I was on the 10th, but right now I'm looking at GOG's reaction to the whole situation and it seems like its a desperate scramble/stress for them to resolve, something which could have been completely averted through the use of better marketing/webpage design.

Prior to the censorship of the Australian version, they did release a press statement on their website saying that all terroritries would receive the 100% uncut version of the witcher and that all countries would get the same version.

Post Australian censorship, they only mentioned that a single country would be affected by the censorship. Namely, Australia.
Now not only is Australia getting the prude version, so are countries like New zealand and Singapore(south-east asia). Thats more than 1 continent affected. The thing is Singapore has as of recently had some fairly liberal laws regarding Games. The only games that can't come in are explicit "Adults Only" titles. So there's no reason singapore and new zealand should be affected.
Oh and these countries were never told they would be getting the cut version, only australia has had that heads up.

"And to be fair, the changes actually do appear to be very small. The quests are still in the game, but Australian Geralt will have to choose a more tangible payoff for completing them. Witcher 2 Project Lead Adam Badowski said the studio was "disappointed" about having to make the cuts but that removing sex as a quest payoff was the only way to get the game onto the Australian market."

Also i read somewhere that we are talking about 1 (!) quest... Don't know if it's 100% correct.

P.S. really mezla1058, grow up and see who is to blame first before start cursing everyone around.

Yeah the actual cut content is small but viewing it from a legal point of view is quite interesting, it inflates the issue to quite a big deal
