A couple of months ago VALVe updated the prices of the videogame Left4Dead to more a fair difference between the euro and the dollar. The English Pound was overpriced.
The prices where: $40,- ; €30,- and £30,-
They updated it a week ago again, but this time they only did the dollar and the pound.
Today the prices are: $30,- ; €30,- and £25,-
Why they made it unfair again is something I don't know. :(
