Is Nintendo an ancestor of Aperture Science? A dummy corporation? We recently recorded the North American voice of the Wii Fit Balance Board, and it bears an uncanny resemblance to Portal's happy little turrets. Even the hierarchy of henchmen follows Portal. Aperture science has GLaDOS, and Wii Fit has a male- or female-voiced personal trainer.
Yes, there are still a few differences. The Balance Board voice -- and we presume nefarious AI -- comes through the Wii and out a TV, while the turrets are all self-contained. Plus the balance board might not be trying to kill us. The verdict is still uncertain, but be warned.
