Besides, games are not 50 € in Europe, they're 60 € or 70 €.
Even those for PS2 are 60 € when they come out. Wii games are 60 € too. XB360 and PS3 games are 70 €. Of course, some of them are sold for less at launch (50 € or 60 €), but I don't think that was the case this quarter. FFXII was even 70 € IIRC.
