The fact of the matter is the pound is doing very well against the US dollar at the moment, so trying to compare games bought in the UK with UK money with the US Dollar is almost pointless
If tomorrow the US Dollar fell to 50 dollars to 1 UK pound it would be mighty silly going around complaining that UK games work out to be 2000 dollars without looking at the overall US economy.
Also given this is in the Nintendo section I've got to ask were are you people buying your Wii games. Last game I picked up was Mario Galaxy at launch and that cost me £24.00 after discounts and refunds which is a lot short of £40.00
