I'm not saying they don't. I've long time said that Steam isn't quite as great outside of the US for the same issues you mention (plus the more widespread bandwidth caps and stuff). The thing is, pretty much all the digital distribution platforms suffer for the same reasons outside of the US.You're still ignoring what I'm saying. Valve does this for their own games as well. Half-Life, TF2, L4D are all 30-35% more expensive for europeans. Their reasoning for it is that we have to pay added VAT, which is a flat-out lie. Point that out on the forums and see how long your post stays up.
The only other thing I was saying is that you can't blame all of the pricing issues on Valve. You can certainly blame their own games on them, but publishers of all the other games set their own pricing, including the jokers that price their games more expensive in other regions.
