Well, it's name. Fans of professional American sports will be used to seeing stadiums named after companies. Insurance companies, banking companies, telecommunications companies. It's a shame, then, that unlike in Japan, none of them are named after video game developers.
Hakata no mori Stadium, in Fukuoka, has that honour, as since 2008 it's been known as "Level-5 Stadium", after the Japanese developers of hit franchises like Professor Layton, White Knight Chronicles and the upcoming Studio Ghibli collaboration Ni no Kuni bought the naming rights (in Yen, not matchsticks).
