i dont know...
gog would say it's devs fault, devs would claimit's gog fault
so far we all had seen how GOG could go bonkers on its regular activities whenever they are rushing to screw up the implementation of yet another whimsical feature that only serves pushing up their Galaxy client
i remember when Galaxy appeared and until it exited beta, i had to suffer a dramatic drop in the quality of any support i received regarding tech or customer support requests i would send, with the ground breaking gold medal of over 2 months for an account based bug that prevented me to successfully pay my orders, a bug that could only be fixed from their side, that i had to relaunch the request 5 times in the two monthes, while i had to pesker a friend of mine to do the purchases for me and gift them to me meanwhile...
so, sorry, but given the whole social profile madness, i am completely inclined to believe the devs who would tell me that GOG is currently having insane delay for generating/supllying keys, rather than think that GOG is prfect and flawless at it and Devs are lying
after all, please consider that bothering themselves to ever provide DRM free version of games is costy, is a risk, and most of all, not really worthes the pain and trouble, considering the major actor's alternative for them that is convenient
some devs/publishers end up releasing games on GOG only AFTER having made the major share of their sale on said platform . Here we are talking of devs who willingly made the choice of proposing DRM free games through GOG only (could have gone Humble, frankly) from the very beginning, during a KS campaign, long before the game ever got released.
And the backers rewards choice for either gog or steam key were locked down and confirmed several monthes ago, so the sheer volume of keys that was needed was known since long ago.
Under normal circumstances, i'd give GOG the benefit of the doubt.
Under current circonstances, given current GOG's agenda (implementing social crapfest, droping trouser and bending over for Facebook as well, rushing everythin they can before GPDR kicks in next month in EU in order to bypass it (which is already a shady practice, if you ask me)... NO, this time at least, i DONT give GOG the benefitof the doubt
And i will remain upset and salty as long as i dont get my GOG key, especially as i paid for it in advance one year ago, and that regular customers could already buy the game on 19th april for same price and play it. As a KS backer, i dont claim or dare to ask for cheaper price or earlier availability (which is, however, usually how it works for most campaign) but at least i also expect not to be served LAST or one week after (if not longer) than everyone else (again... RIOT: Civiil Unrest incident... took me 2 months and several mails to get my key... while i backed it 3 years before release)
sorry if my words seem harsh and are disappointing you, but it seems that it's harder and harder to stick being a drm free customer, and i have to resign on being treated not as second class, but third class customer..
