Again, if you are playing RPGs solely for the story, why are you playing them at all? Books and movies have RPGs beat on story every time, for content, presentation, everything. If the game doesn't matter, why bother with it at all?
I agree that someone who is interested should take a shot at learning some Japanese and giving a J game a shot. It might be fun. But if they don't like the experience, that's fine, too. We shouldn't begrudge translation efforts, either. Different strokes for different folks. There's room for all of us.
