Well, I'm not sure if Kishi approved of all of Yano Takeshi's (the author of Shikamaru Hiden) ideas.Damn, i can't believe people even praised Sasuke. Naruto was the one considered the hero of the war though.

Kishi himself probably would keep Sasuke's involvement in the war a secret from the masses. Kishi probably make it so that only the shinobi who witnessed Sasuke's actions in the war would know.
Sasuke doesn't care about glory, of course. He's all about working in the shadows and being low-key. So I actually disapprove of Yano Takeshi's decision to make the masses consider Sasuke, along with Naruto, a hero and living legend.
