"What % of the US game market would be left if they had to pay these prices?"
Please pretty please learn something about exchange rates. Direct conversion is pretty much meaningless (and are made dozens of times). Use Purchasing Power Parity adjusted rates for real conversion. (PPP 1$ ~ 1E that means over a wide variety of goods you get as much value for 1$ in the States as for 1E in Europe).
Why is that so?
The value of the dollar (in relation to Euro/pound/A$) has dropped by what 30% in 2 years?
That doesn't mean that 60$ games are suddenly 30% cheaper for Americans than 2 years ago. For Americans the prices stay the same. There wages aren't in Euro neither. Over time the differences will come together.
Besides in Europe VAT is included in prices and high and in America VAT isn't included and low. Europeans generally get ripped off by their government anyway.
