Although it cannot be denied that Visual Novels are a good way to give the rest of the world a peek into the Japanese culture, for me it's much more than that. There are several other things that got me hooked to VN's besides the Japanese culture.
The characters' appeal is defenitely something important to me. From their personalities to their tastes and their looks, you can always find so many different stories, endings and paths.
I like the idea of being the one in control of my character and make the choices for him based on my personal feelings.
Another thing is that you can also make a mental picture of character's personalities and tastes and predict how they will react to the things I do to them.
Being a dating culture nerd, it's also especially interesting to see the Japanese dating culture, how they act on dates, what they like as gifts, the traditions they have and the whole concept of "relationship".
The idea of having a Disney Visual Novel does not appeal to me at all. It's too much of a change from what we're used to. That would mean no super kawaii 2D anime girls on my computer screen (I'm joking about this one but deep down maybe I really mean it) and there's won't be the challenge of trying to on dates on the Japanese way,
