"It's kind of funny," Pacini said, "because when we were first talking about the game there weren't actually cores yet. We had these cool robots, and it was like, ‘Hey! I get to surround this world with cool robots. This is awesome.' We're like, ‘OK? How do these robots work?'"
"So we're doing the anatomy of the robot, we're like, 'OK, well you could pull them all apart, put them back together, like what is, how do you, what do you relate to the robot as? Is it the head? Is it like a microchip? What is the thing?" So, we had come up with, ‘Oh, it's like a brain that everything snaps around the brain.'
"And then Inafune-san's group is like, 'OK, that sounds cool. But what about this?" he says with a laugh. "And they were like, ‘Boom! And it was like core!' And we were like, ‘Awesome!' Solved the problem and then woosh, we took off from there."
The true nature of the cores, however, remains a mystery — one that astute viewers might be able to suss out.
"We'll be able to talk about that more pretty soon," he said, "but everything about the cores is intentional, even down to the size, the color, where they go. There's a very strong purpose for them. We're really excited to start talking about them."
