I don't know why people talks about Murayama like he was a god.
He "created" the original plot and some charismatic characters but...that's all.
I mean, do you think they couldn't make a great Suikoden game with Yuber and Pesmerga whithout him?
Any writer could do it...any of us could do it. Is just Konami didn't use them (i supose its to create expectation)
Imagine, they readmit Murayama. First reunion...
Murayama: Well, the next game will set up in Harmonia, Hikusaak...
Konami chiefs: No
Murayama: Well, then Yuber and Persmerga...
Konami trolls: No
Murayama: Then, five years after the battle on grasslands...
Konami: NO
Murayama: Well, then the game is a prequel in a new country, new random true rune (just one) Viki and Jeane and some other old random character (Like Gantetsu for example) would appear.
Konami: Proceed
I mean, there isn't any writter problems, the Suikoden V script is the quite good for example. The problem is Konami restrictions.
So, Murayama presence itself doesn't guarantee something, if konami doesn't release the restrictions is the same.
So for me is more important Konami stop trolling us than hire Murayama
