Bas: It's funny that you point this out now, as Steam can fuck right off now that they've decided on scamming extra money out of Euro customers.
In fact, that's not the fault of Valve. Valve only caved in to the wishes of the major publishers, which want to preserve their regional price system, in which Europeans pay higher prices than, for example, customers in the USA. Europeans are no longer allowed to take advantage of the lower dollar value (against the Euro). They are forced back to their "traditional" higher prices. And now, publishers like EA can open up their back catalogue to platforms like Steam, because now, they can keep on ripping off us stupid Europeans.
