As much as it sucks for those in Europe, no one has a 'right' to ask for Steam prices to be the same in different regions. Steam is a company just like any supermarket chain. If Tescos started charging twice the price for something, you'd just shop elsewhere, wouldn't you? Not start a 500-page long thread on the Internet in a crusade to get them to lower their prices. In short, they're welcome to charge whatever they like for games, but if those higher prices make them less attractive than retail stores then it's only Valve who's losing out, not the consumers.
