After a trip down to a local Gamestop the other day to pick up soon-to-be-controversial suicide romp Persona 3 (complete with bitchin' art book as a pack-in). a gamer noticed one small detail on the back of the box that blew his mind-and not in the way the game designers had intended. He noticed that under Memory Card it required 67MB.
Now if you do the math 67 ÷ 8 = 8.375. That means you would need a total of nine memory cards.
