Cavalary: Welcome to the "wonders" of regional pricing, made standard for electronic sales pretty much since they appeared. GOG used to very firmly stand against it, was their second clear, specific principle, then gave up on it.
Nothing to do with what Pheace says, though he'll keep making a case for it now that the opportunity presented itself, it's just a matter of what the publishers can get away with, this 1 USD = 1 EUR "norm" staying the same through the years, whether the difference between the currencies was 7% or almost 40%, and regardless of the varying tax rates in countries.
uhuh. 'Nothing' to do with economics. I'll easily agree they'll take their opportunities where they can. You can complain about that plenty without ignoring the realities behind the numbers. Simple fact is, many people mistakenly think publishers are taking the entire extra value of the Euro over the dollar price, and that's simply not true. It used to be an issue, when the Euro was ~40% more valuable, so it was more than the VAT costs. It's not anymore these days.
