A random thought came to my mind tonight. I was looking at some old maps from previous Phantasy Star games and I just thought, how big are the worlds. Its understandable due to the Genesis cart limitations, but looking at the Phantasy Star IV Motavia map, you basically get a large continent the size of.. lets say Asia, with small islands about the size of Japan nearby.
Now just thinking theoretically, if the games were flushed out more, do you think there would be more continents? Could there be more traces of Motavia that the Great Collapse has hidden from us on the other side of the planet? Its just a curious thought.
