Why Naruto didn't gain the Rinnegan is a mystery. i think it's pretty obvious that it's because he doesn't have the Sharingan. the rinnegan requires the unity of the Senju and Uchiha, after all, and naruto misses the Uchiha part. Besides, it's also because Hagoromo wanted to share his power equally, and so gave each part of his power as it made sense: Naruto his Senjutsu, and Sasuke his Eye power. Just as it had been divided across his children.
