Vlada_LR: I wonder that as well, it's really annoying as everything is more expensive for me (as I have noticeably better exchange rate for dollar, than for goddamn euro).
It's not like they are actually "expensive", with such a cheap games difference is small, but it's still annoying. I really don't get, why I can't simply choose currency myself.
I was afraid this is going to happen, after I was forced to use euro for purchasing Witcher 3 :/ I was told, it's because of publisher and gog have no control over it. I don't think they can use that excuse now, though.
You can always change back to USD if you prefer this currency. Just take a look at moonshineshadow's screenshot. :)
