At the Christmas party that Sega had to launch PSZ, there was a question and answer session. One question asked was "Is there any connection/relation (story-wise) between Phantasy Star Zero and older Phantasy Star games?" to which Sakai answered:
"We announced before that there was no connection between PSZ and the other PS games, but... if you do the quests after you finish the game, and read the story text carefully, I think you will discover that there is some relationship there."
What do you think?
