I never would've made that connection but I can somewhat hear what you're getting at. That's amazing and wonderful.

There's several PSO/Phantasy Star in general references buried in the game actually, I used to have a list on hand but right now all I can think of are the Battle Sprites being basically Mags with skills. And I guess Hahn is a character in PSIV?

There was another one that Nick himself mentioned but he apparently took it out because it was too obvious. :(
