What's there to discuss?Yamaoka's music is almost legendary...The man is a genious when it comes to video game music.The series wouldn't be as successful as it is today if it wasn't for his music.
I think it was a real blessing that in SH2,great minds like Tsuboyama,Owaku,Sato,Ito and Yamaoka happened to be together to produce one of the best games of all time.For me,it's a combination as great as the Sergio Leone,Enio Morricone Clint Eastwood team.
Unfortunately there's almost 0 chances of the SH2 team silent to ever be together again.
I have to say,that the series are going downwards ever since Yamaoka became a producer.I have recently read an interview in Gamasutra where he tried to convince the journalist that there are some members of the original team silent that they are "kind of helping" with the production of the new SH game Homecoming.As the interview progressed though it was clear that he was lying.The only member of the original Team Silent involved in the new game is himself.
I think for the series to return to it's former glories,Yamaoka must either return to composer only duties (most unlikely) or leave the franchise entirely.
