I also want to point out that not every company is as greedy as Paradox.
Many companies do not set €1 to $1.
There is a website called steamprices (google it because I fear of getting an infraction for posting an external link) which lets you compare Steam prices in different currencies.
Even big companies that publish hits like Total War Rome II, Skyrim or Football Manager 15 acknowledge the fact that the Euro is stronger than the Dollar and therefore they have adapted their prices accordingly.
Even upcoming titles Like Borderlands: The Prequel have different prices for the European market: $59.99 compared to €49.99
In fact, Paradox is just abusing Europeans by charging extra high € prices.
If you think this is enough to declare what company is greedy and what ain't then you are looking quite narrowly at it
The thing is, the whole €/$ problem is VERY prevalent on Steam, to the point that I am not buying that the problem is in the Publishers. Too many games follow that policy and the problem doesn't occur, in such a magnitude at least, anywhere else... and that's without mentioning that Steam itself defended the whole $ = € deal. There was a lot of discussion about this, none of them having anything to do with Paradox Interactive.
And the big companies are really a horrible example: it is easy for them to buy themselves special privileges, all while looking like a nice and honorable publisher.
