A-Pock: you couln't play ghostbusters or The Witcher outside the allowed countries either.
Actually, yes you could. This is the *first* Steam store sold game that is restricted by IP. For the record, I had the Ghostbusters game gifted from a friend in the US on its day of release and it plays perfectly -- as do all my other games not sold over Steam in Japan.
Just not DA:O. And most likely, no new games either.
A-Pock: However that might have been an honest mistake, games are generaly not released worlwide at the same time so steam used the only IP it had available (the japanese one) to check if the game was released. But I still thing the country where the game is bought is what should matter, hope they fix that.
Sadly, according to replies from support they are NOT going to "unlock" the game for Japanese IPs. It will be forever restricted here. Which is why they are offering refunds. But refunds are simply not acceptable.
