Apparently they wanted to make a Japanese styled game, or with Japanese styled art. I wouldn't automatically say animesque, but it may be the best catch-all term. As she wanted it to be English (British) in tone and everything, they were out of the running pretty quick. If she did sell them the rights she would be a lot less wealthy, though through creative accounting and flooding the market with merchandise, Warner Brothers grabbed the vast quantity of all income not related to books. I also think the Harry Potter game series would be a bit... Meh? Not sure. EA Games had the rights for the games I think, and whoever made the ones for Game Boy and Game Boy Advance were... well, they could only work with so much. Would the series be only one Harry Potter game a book? And would Nintendo only buy the rights to use it in video games? Considering how the rights to Pokémon are split between three companies, I imagine that Nintendo would be happy to pay a little less and only get the rights for games. Just so long as they make sure the contracts give them rights to trump movies, so that they cannot be sued by some American film company if there are similarities between their products.
