Connection between Wren from PSIII and PSIV?

[Valinne]

Deliberate, just like the naming of the planets. There are a ton of easter eggs in PSU to the original series. Alot of the characters are based around classic characters, and Fulyen is one of them.

Ah, I've been noticing something similar, like the relationship between Karen and Mirei, Tylor and the Landeel, Rutsu, and some other things here and there.

Just want to clarify really quick, Mieu wasn't mass produced, correct? It seemed as if she was a lone, advanced model.
Edit: Whoops, almost forgot about that broken one in the desert.

I wonder how popular the original series is compared to the PSU and PSO series now. Will they ever make another turn based game? That might be a question for another time and another topic...
