so in general newer visual novel reading people will tend to read hoshi memo or some other newer vn made around +2007 where generally art starts improving and becomes less fiss-eye and out of proportion.
but if you start with early vn dating around ~2000 where art was yea you know since you saw it already probally you would care less about the art and more about the story but also it mainly depends on ones personality and preferences its not like we can say we all must read visual novels for there visual part and not there story.
