Since I live in Norway games are presented in NOK (Norwegian kroner), and that is ok by me.
BUT if I go into the game catalog there are sorting by Gametype, Price and Availablility. In the Price section it says: $10.00 - $29.00 (which would be 60 - 180 NOK). If I click this link I will not find games in the 60 -180 NOK range, but in the 10 - 29 NOK range. Since most games cost more than 30 nok, all games are sorted in the $30 + range. This is clearly broken.
Another thing that is extremly annoying is that while Impulse will stop me from buying most new games (I am not an American), it still shows all the games that I cannot buy (even shows the Norwegian price).
