Emotion Engine. Konsole - PlayStation 2

W lutym 2003 r. Sony ogłosiło sprzedaż 40 milionów konsol PS2.

W tym czasie PS2 była w okresie swej świetności, GameCube nie podołał wielkości Sony, a Xbox Microsoftu powoli zaczął szokować grafiką, choć na pewno nie ilością sprzedanych konsol. Zaczęły też oblatywać świat pierwsze, dość skąpe informacje o PlayStation 3... ale to już zapewne inny rozdział w dziejach konsol.
