Hmmm… your name is going to give bad vibes around here.
Most of the people who play bishoujo games games don’t speak Japanese. The games are made in Japanese, so that’s the language that you hear. The audio track is a very important part of the game. If it were cut out and replaced with English diolauge you’d almost be playing a different game. Really, you wouldn’t want that. Now, there are some people here who are creating their own games. They will be in English from the beginning so you might want to check it out. I’m not sure if there will be any spoken English, though. The Japanese game “Casual Romance Club” has a spoken Japanese and Engrish track. This probably isn’t what you’re looking for but if I didn’t mention it someone else would.
