Yuji Naka on Sonic Heroes Original Soundtrax:
We have set 2003—this year when we celebrate the 12 years after Sonic was born—as the Year of Sonic and provided various Sonic products with the feeling of appreciation towards the fans who have supported Sonic until now and with the meaning of introducing the character called Sonic to more people. The game merchandises are, of course, the anime Sonic X, comics, and the like, as well as the last project that concludes the Year of Sonic is this Sonic Heroes. I think that this game in which all Sonic characters appear was completed as a production that anyone from old fans to the beginners who touch Sonic for the first time would be able to enjoy the world of Sonic. We want to continue raising Sonic as the world-beloved character, so please support him even from now on.
