So, from every PSO game to another, it always seems to be different.
In this game it seems CAST's are "Cyborgs" of sort, with human minds/brains, just tranferred into Robotic bodies. But from playing PSO games long ago, I always figured I guess that CAST's were just offensive robotics designs with the purpose of just that, "Full offensive", and this is why many of the previous games did not allow CAST's to use Magic/techniques.
I've been watching the Anime, AFTER I beat the NA story (played JP story only so far), and in this version Risa, the crazy Robot chick actually sort of explains that she was once a little girl, but her body wasn't suited for photonic arts, so, her mind was actually transferred to a robot, thus, is what we call "CAST's" in this game now?
I ponder this, again, haven't fully played the JP version, and just now after finishing episode 3 in game, am watching the anime now, although there's no mention in the Anime how Risa came to be (as of yet).
So what really are CAST's? Cyborgs with human mind intigration, or... Just robots to do what they're told? We already know from the game and Anime/Manga "Code Abyss" Affects everything.
Just wondering about other opinions. Cause as an Oldschool player, I guess they never really went in depth with CAST, aside them being Robitics with no Magical force at all.
