So, let's put some facts on the table...
Kamiya had nothing to do with MGR. He is part of Platinum Games, but he was not part of the team who did MGR. None, nada, zip, zero...
... Seriously? I hope they will do better with the story then. I mean, what Kojima is mostly known for is his epic storytelling skills and how he put it into videogames. The Metal Gear Solid series is proof of that! But MGR... it had a really tacky and unserious story. I can't tell you guys how disappointed I was about it too many times... And I am not hating for the sake of hating, I was disappointed because I am a fan of Kojima, I am a fan of the Metal Gear games and I was really hoping to get a cool story about Raiden in this game. So Kojima, pull yourself together if you're going to make a sequal!!!
