That's the EU edition, so can we New Worlders use it?
And it probably substitutes all the blood with candy or some shit like that.
Did you go to their website? For example I see this version: Dark Souls: Prepare to Die Edition (NA)
for $20, so $16 after coupon. GMG shows games and their different versions plus prices depending on your location.
Well if there were region restrictions they weren't for NA region obviously, as Nuuvem is a Brazilian store. ;)
Rule of thumb: if you want your games on Steam, simply get Steamworks games from there, which is always stated on the store page if it is one. And I don't think I heard of any region restrictions on their Steam keys so far.
Steam has been known to remove the game after activation if they feel you bought a cheap foreign key. It is against their terms of service. Most people get away with it but generally it's a good idea for US citizens especially to buy from US stores.
Missed your post before. Actually I did hear about such a few times, but never talked to someone directly who happened to experience such things. I do admit that Steam states in their TOS
that they won't allow you to use a VPN or similar things to disguise your region:
"You agree that you will not use IP proxying or other methods to disguise the place of your residence, whether to circumvent geographical restrictions on game content, to purchase at pricing not applicable to your geography, or for any other purpose. If you do this, we may terminate your access to your Account."
However I don't see how this would apply for example to getting a game from a friend living abroad or to buying a retail game during your holiday in Brazil. They don't even know how you did acquire a retail key. So in fact they simply add regional restrictions on certain (mostly newer) titles to circumvent this in single cases. I haven't heard of any case where a retail key that was bought from a legal Steam key reseller was revoked later on (using a VPN to buy from Steam itself but in another country's store is a completely different story!).
Long story short, I see your point and if a store (like Steam itself, or the UK based GMG, or the Sweden based GG) offers me games and their prices based on my current location, it wouldn't be right to disguise my location when buying to get different prices. However IF a shop doesn't have a localized version of their store and offers customers worldwide to buy from them, I don't really see the problem here.
And I didn't wanna start a discussion here, I just thought your comment that people should strictly buy things only in their own country to be a little bit too strict. And with my initial comment I simply wanted to point out that Nuuvem is NOT in NA region, because they are a Brazilian store and thus surely not in North America.
