Princess Maker
Earlier, there was an entirely different "Princess Maker 4" in the works. Under development at Ninelives, the game was to take place in modern Tokyo rather than the medieval world featured in the final game. This project was eventually abandoned due to Akai's health issues. However, the concept went on to be the basis of "Princess Maker 5", including the modern Japan setting and the fact that Cube can transform himself into a dog.
