The Wii isn't region free to make sure that Europeans buy PAL copies of the games, because otherwise the long time of work for the translations would be a waste.

Also isn't the value of the U.S dollar pretty low compared to the currency of the Pal regions?

 

thats what i was about to say, many people would just buy the NA games because they are cheaper
