I currently own all three Shadow Hearts games even though I've only played the first and only about halfway through. I understand that Koudelka starts the entire series. I've done some research, but I can't seem to find how relevent Koudelka actually is to the Shadow Hearts series. I'm not asking if it's a good game. I'm asking if playing it will make playing the other Shadow Hearts games more understandable or enjoyable. Anyone played it? Anyone know?
