If you're talking about the digital version, then due to nature of content the digital version of the game is currently banned in Germany where European e-Shop is officially registered. This is making it impossible to officially distribute the game in European countries and also in Australia and New Zealand. We are currently working with our partner and local authorities to remove the ban as soon as we can.
The game is available digitally in the US and Asia, and the retail version is available worldwide (except Germany)
