Taken from an interview on Sonic Heroes.

Sega: Is there an advantage to having a portion of the development team based in the United States?

Naka: Well, since Sonic has fans worldwide, it is very important for us to know the culture and the fans not only in Japan, but in other countries as well. Plus, I think Sonic enjoys the laidback lifestyle of California.

Pff, no wonder Naka left. Sega only cares about JAPAN! Who gives a rats ass about those fucking filthy baka gaijin of the Americas!?

It seems as soon as he left, Sonic didn’t matter to anyone anymore. I wonder why….
