In North America and Europe Sonic Unleashed is exploding on every viable console on the market with a PlayStation 3, Xbox 360, Wii, and PlayStation 2 version that Japan isn't getting. Sega of Japan plans to release Sonic: World Adventure (renamed to better fit Sonic's journey around the Earth and downplay the Werehog thing?) only on the PlayStation 3, Xbox 360, and Wii. The PlayStation 2 port will be completed before Sonic: World Adventure launches in Japan so this begs the question why is Sega passing on it? It's not like Sega Japan is abandoning the PlayStation 2 entirely. Thunderforce VI comes out on Thursday in Japan and unless Sega has anything secretly planned it will be the final PlayStation 2 game published by Sega in the region.

In an interview, SEGA Sound Team lead composer Tomoya Ohtani revealed that Sonic’s global music success didn’t come from chasing trends overseas.
I think this is how Japanese devs need to think. Catering to the west is a terrible idea. I personally, seek out Japanese developed games because they bring a unique experience to gaming. They just stand out more that way.
The sonic music is iconic the mega drive games were some of the best on the system but i wouldn't say they were free of western influence especially since 3 was composed in part by Michael Jackson
But honestly most of the crush 40 soundtrack music lives in my head rent free
Uhhh that's a strange thing for him to say. Even in the interview he admits to listening to a lot of western music.

Sonic Unleashed on PC? The Sonic community managed to do just that with with the fan project "Sonic Unleashed Recompiled."
Actually the torrent is up and you do not need to own the 360 version of the game. Also it will never be taken down.
u gotta give the hardcore fans credit, they are committed to fix segas 3d sonic games ha.

Team Chaotix have been playing comic relief for Sonic since their reintroduction, but they have the potential to carry their own game.
But I'd rather have Thunder Force VI, anyway. :D
