No they should just be forced to pay the same amount that the rest of the world does.
Either way, just this one man's opinion. Im sure no one is listening and video game companies will continue to shoot themselves in the foot with games like AC09 with no CDkey for online play etc etc.

You can't force people though when Piracy is always an option. If piracy was such a problem the companies would stop making games and consdiering they keep churning them out, I don't think there is so much of a problem.
