The same reason why old JRPG don't have the voice. Remind me about Suikoden 5 and you can see the animation of MC angry but with no voice (talk about lame).
I have just finished playing Tokyo Babel. It was really fantastic and made me cry. Now I am playing Shadow Pygmalion but I wonder whether I will like it like I love Tokyo Babel.
Personally I don't mind high schooller as heroine since I know that this is fictional, as long as they are interesting (not innocent, spoiled, or cry baby).
I think it's in decline. Overall, many things from Japan is in decline (anime, games, manga). No reason to think visual novel is the exception. Just my opinion though.
I really like it. The second episode is much better than the first one. It just that the ending is quite anti climax. Cannot wait for episode 3 though.
I feel sad to hear this. Personally I don't mind people whom cannot afford it (due to their low income) to pirate it. But for people whom can afford it, I hope they will buy more VN to support the company.
