Everyone gets a perfect reality tailored for them. Not in the fluff and rainbows kind of way, but in the sense that their individual world is based around making them the hero of the story. He essentialy changed the game enviroment from PvP
to PvE, and thus everyone is able to overcome and win, unlike reality where some people by necessity become
losers. LITERALLY EVERYONE gets what they want. Not everyone is a titular character, unlike naruto.
Naruto has shit character development. He literally has more character development in the first two arcs than the rest of the series. Never does he have to change in his views or outlook on life. Never. Instead the villains do. Nagato, Obito, Gaara, etc. He doesnt have answers to anything but the narrative requires them to bow to his will because his plot shield. You just self insert so you think hes a good character while the truth is he lacks any depth and is the biggest attention whore in the seris by far. Everything naruto does is for attention (hokage, sasuke) because thats the only thing he cares about.
