GOG's had some pretty big changes made recently. No worries though, it's all good.
The first of the big changes is one that was discussed earlier but then scrapped. Regional pricing means that customers in countries other than the USA can now see prices in currencies other than just American dollars. Currently Euros, Pounds Sterling, Australian Dollars and Russian Roubles are supported. The plan was previously scrapped because just as with Steam the prices in other currencies didn't exactly match those ones in dollars, but GOG are now getting around this by making it an option to choose to pay in a currency other than dollars. They've made the prices more equal too, although where the publisher of the game follows a different regional pricing you'll be able to get the difference refunded in store credit if you choose to pay with something other than dollars.
The other big change suggests that GOG are trying to beat Steam to the punch with their upcoming support for movies and televisual media. There are now 21 documentaries about gaming available for purchase on GOG, some free while others are currently discounted under a launch offer. There's also plans to bring more to GOG but no one seems to want to be the first to try.
"DRM-Free distribution is not a concept their lawyers would accept without hesitation. We kind of felt that would be the case and that it's gonna take patience and time to do it, to do it, to do it right." said GOG
