Like I said, the game is not out yet, it got pushed back and the release date is now November 17. I think that would explain why you aren't seeing it in stores yet - it's the same here in the Netherlands, where shops don't usually advertise relatively unknown adventure games very much.
If you're looking for a reliable online retailer to get it from, I'd recommend Amazon. But the game should come out with Sweden, since
there is an official publisher for the Nordic countries.
