I recently started the Japanese Version of this game over on PS3 and I decided to use this walkthrough, especially since I saw Starlight126 had wrote it and I have followed many of his amazing guides before. I've actually played this game multiple times in the past but I couldn't remember a lot of the side missions. Luckily though, Starlight126 chose to do a page in this walkthrough for every side mission and how to complete each one which is optional on Xbox 360 but on PS3, you need to complete every mission (each one awards a trophy) so this walkthrough was just perfect

Seriously, amazing work! Big thanks!
