General Visual Novel Topic

if you call visual novel something that has no ero content, then i can agree with you. But in this meaning of the term, there are VERY few VNs compared to the amount of eroge.
I’m gonna quote a protag the everyone knows: Okabe Rintaro. Yes, he has a very outstanding personality compared to other protagonists, but his world view isn’t really explored in the game. We can know a lot about what he feels, but not what his opinion is.
