^ Most of nintendo's games are from Japan and they also cost as much as other 3rd party games made in America. I don't think the import costs are that high or anything to really make a difference.
Wii is also 250 euros here which is a lot more expensive then $250... But meh the average West Europeans are probably richer then the Americans anyway.
I thought it was a well known fact that $1=€1 in the gaming industry... Sadly enough...
