Indeed.
The writing in DanganRonpa feels more in line with Corpse Party and 999 to me so far. I think the Persona comparisons that people keep making are a bit off, in my opinion. People probably make them just because of the vibrant colour scheme (Which isn't really a Persona thing, but people think it is because of P4) and the fact that it's a group of high school students in a high school.
I appreciate Persona's writing for what it is. Like I say, it feels genuine.
Wouldn't you just call that depth? Like each character has more depth than the average Japanese video game character? Seems like a better fit than genuine. Like all the other characters are fake or something.
