With Heroes, I got the impression that started of with a detailed story (like Adventure 1 & 2). But then they wanted the game to resemble the classics (like Sonic 1 & 2) and so came up with a bizarre compromise, where the story has lots of details that the game just rushes through leaving the final experience feeling unsatisfying and rather muddled.
They are selling three different Sonic Heroes script books in the same listing if that's what you're asking. One book is story content, the other two are hint content, which is basically everything heard in-game.
