For what its worth I have the game right here and on the box it says 'Project Zero is a trademark of Tecmo Koei Games Co. Ltd.'
Regardless of the exact nature of the relationship between Nintendo and Tecmo or the IP ownership, that wasn't what my previous post was about so I'll clarify:
- Tecmo is the developer, Nintendo is the publisher.
- Nintendo Europe localised the game into five languages, including English.
- Nintendo America have (so far) passed up publishing a game developed by Tecmo.
- Contact Tecmo Koei America not XSEED Games.
- Make mention of the fact that some kind of deal between Nintendo America and XSEED Games was made for The Last Story and Pandora's Tower.
- Ask Tecmo Koei America if they would consider entering into a similar arrangement with Nintendo America so they could publish Project Zero 2: Wii Edition in North America.
The worse they can do is decline to put it out themselves. The best outcome is North America get the game and any sales no matter how low, could help ensure future Project Zero games are released internationally.
