Geralt_of_Rivia: There is a huge problem with this approach: The content industry knows the tactic of baby steps very well because they have been practicing it for many decades by constantly extending and tightening copyright laws. You can not have region restriction without controling them. And that is only possible via DRM.
I can tell you what will happen when GOG allows regionally restricted movies. There will always be some guys who circumvent the current control mechanics. At the moment it is merely an IP check which can be easily circumvented with a proxy or a VPN. As soon as the studios can prove that people outside of the allowed region are buying the movie they will scream bloody murder and drag GOG to court. Of course they will choose a country/city where the judges often rule in favor of the content industry.
There they will tell the judge that GOG contractually agreed to sell their movies only to specific countries (they show the contract as proof) and that GOG has violated the contract by insufficiently checking the buyers country and demand that GOG implements better protection (in other words: DRM). With a good lawyer they will most likely get a decision in their favor. And with a court order to implement DRM to uphold its contract GOG can not say 'No' to DRM any more.
Perhaps Dalthnock hasn't been here long enough to know better but you should know that this isn't some theoretical BS. It has happened to GOG before already. Remember the Witcher 2 incident. Bandai took GOG to court multiple times and got decisions that forced GOG to implement regional pricing (Witcher 2 was the first regionally priced game on GOG, long before regional pricing was introduced.), to implement IP checking (Because GOG simply trusted the country setting of the customer which wasn't good enough in Bandai's book.) and to stop removing the copy protection from store bought Witchers via updates.
And if you think the same thing won't repeat with movies you are gravely mistaken. Movie companies are known for such tactics far more than IT companies.
Thanks for bringing this one up - I remember postponing my purchase decision of Witcher 2 because of that. I think it was $75 US in Australia at launch, while USA got it for $49.99... And at that time it caused some controversy here. At least GOG guys were trying to be fair and were giving the difference away in gog.com catalogue games... Recently there was an issue on Steam when the pre-orders opened for Beyond Earth the game was US$49.99 and in a few days it jumped to US$89.99!! Almost double the price because, well because it's good to make money of those "rich suckers" down under!! Steam didn't want to give any explanation or refund or anything... You want to play the game - well then pay and shut up... Therefore I'm trying to buy my games at GOG.com only....
