Rika/Fal was always my favorite :3 i drew this kinda randonly cuz 1) i wanted to draw Rika anyway and 2) i recently learned she had a bday on 9/24 which was just incidental timing, ahahah. also, I noticed a slew of Nei bday fanart on 8/30 but not so much for Rika for some reason
Yes apparently! It's on the PS wiki somewhere, they all have Earth month/day birthdays somehow. This is all news to me too LOL. I saw some birthday fanart for Nei, thought the same thing you did, looked it up, learned that Rika's was coming up and then used it as an excuse to draw her :D
I guess that's as far as they went when they wrote the lore of the story. I don't blame them, that shit's hard. And learning the kind of stuff I do about physics, nature and astronomy, the inconsistencies in how things function in those worlds are..... way off.
Trying to work on my own story and whatnot, I've learned the most planets that can fit in the goldilocks area of a star is at maximum, 4, and they'd really pretty much have all the same composition most likely. So having a desert planet, and ice cold planet and an Earth like one would be implausible, as well as the amount of days for each planet to experience a year would go up significantly, so there'd be confusion between peoples as to how old who was on what planet.
Writing stories is a mess :(
