The conversion to Euros is not to blame, IMO it's a deliberate decision on the part of the publisher to charge Europeans more for the same product. In a couple of weeks the game will be available in brick-and-mortar stores in Europe for the usual retail price of 40-45 Euros. If potential buyers start downloading the game for far less, that will hurt European sales. It's called cannibalism in marketing jargon.
We can't have that, can we...
It's not just
A Vampyre Story. Goes for a lot of games, publishers, sites. Doesn't even matter where the game was developed. We also pay more for European games, often much more. There's nothing I can do about it, but I refuse to reinforce this policy. So I buy from US stores like InteractCD and I only download games when the site charges everyone the same price.
