Need region restriction option: NA

A region where certain people support the idea of the ban on immigration of Muslims.
But all seriousness I'm not sure what Deep Silver is beefing about.

It's the 'let's be a bunch of miserly f*cks and make sure those Europeans pay the extra ~4-12%' region (w/ special +25% exception for UK, and -25% costs for Norway, thx to technoviking)

just like how most games are converted directly from dollars into euros on steam =p

Non-EU region. Deep Silver and Capcom have separate EU regions, although Capcom only for some games. The trick is that even ROW keys get rejected for Europeans for these ones. Well, sometimes. Sometimes ROW works. Kinda hit-and-miss-and-memorise-which-is-which. Like with a few region-specific game versions.
I… never managed to find a reasonable explanation for this. It's not because of German regulations (they usually just get a separate repo anyway), and not even naming conventions (some franchises had a different name here like XCOM running under the name UFO, but that is a thing of the past).

Hey, happy cake shipwreck day to you! =:D

Amazon's NA only, it says this specifically about regions, or just says that purchaser must be in US?

Paypal's gift cards on their gift site or on ebay, are restricted to buyers w/ US paypal accounts only, even though they work globally (outside of a dozen or so countries in SE Asia/Oceania area).

But, yeah, like talgaby said, Capcom would be the other publisher I can think of that does this. Do you know of some others?
