GeraltOfRivia_PL: Do you consider GOG an obscure store like Itch.io, or a major store like Steam?
The designation of "obscure" is somewhat arbitrary and subjective so there is and can be no objective conclusive answer to this question without a clear definition of obscure.

Definition of obscure
(Entry 1 of 3)
1a : dark, dim the obscure dusk of the shuttered room
b : shrouded in or hidden by darkness standing obscure in the deepest shade
c : not clearly seen or easily distinguished : faint obscure markings
2 : not readily understood or clearly expressed also : mysterious a slough of pretentious and obscure jargon — Philip Howard
3 : relatively unknown: such as
a : remote, secluded an obscure village
b : not prominent or famous an obscure poet
4 : constituting the unstressed vowel \ə\ or having unstressed \ə\ as its value
GOG is neither dar or dim, shrouded in or hidde by darkness, nor are they not clearly seen or easily distinguished, nor are they not readily understood or clearly expressed. GOG is not relatively known, nor a remote secluded village, nor are they non-promiinent. For the latter as an example GOG.com sold the most copies of The Witcher 3, one of the best games of all time known and loved by gamers around the world. It's pretty hard to be "not prominent" or "obscure" when you sell the most copies of one of the most popular video games ever made.
And finally, GOG Is not constituting the unstressed vaowel or having it as it's value.
So by dictionary definition, I would say that GOG Is objectively not obscure. As they say, when in doubt, consult the dictionary! :)
