All historical Japanese story was cut and replaced with a fictional story, all historical names were changed to silly pet names, 4 playable characters were changed to non-playable characters, difficulty levels were tweaked, many skills were changed and removed, some stages were changed heavily, "Prime Attack" system was added, etc.
