Gilozard: It would be super irritating and not at all the kind of thing a business should do.
Pranks like that are only funny for some people. Not everyone. For a store to do that would be kind of a betrayal of trust (by not having what they say they have) and might actually cause trouble with truth in advertising laws.
skeletonbow: To some perhaps, but it'd be funny as hell and they've done a few things before of a nature like that (see screenshot posted above by moon).
Even the monks video that got them in trouble years ago, the followup interview question sometimes later on video sums up GOG's sense of humour.
So you have GOG pulling a massive hoax prank publicity stunt, pissing off tonnes of customers, apologizing in a joke video that isn't taken too well by people either, and ultimately the publicity of it all worked in the end, and then being asked in an Interview why they thought the monk thing was funny and you get:
https://www.youtube.com/watch?v=MWYcsvPeqxk For those who don't know who that is in the monk robe, it is the CEO of CDP and GOG Marcin Iwinski. I think he has a super funny sense of humour and overall personality. :) Even in videos they do where he's not saying something funny you can see him laughing and goofing around a bit to the side where it's obvious he has a pretty good sense of humour and thought of something funny that he might or might not share with everyone. :)
Personally, I'd like to see more of that humour. Not to a controversial hoax extent like they did before but just some good old fashioned fun kind of humour to keep the place alive.
A game distributor isn't a place where everyone should be wearing a suit and tie with their underwear starched. :)
It might be funny to some. But 'some of our customers might laugh' doesn't mean it's a good idea. What you call 'good old-fashioned fun' other people might call 'insulting', 'false advertising', 'mean', etc. Not everyone is you.
Game development is extremely lawyer-heavy, and distribution needs way more lawyers than development. Contract lawyers (employee contracts, contractor contracts, engine and any 3rd party library licenses, art and music rights), copyright lawyers, patent lawyers (software patents mostly), all those trademarks, lots and lots and lots of international lawyers. Did you really not know this?
