The Emotion Engine is the name of the Central Processing Unit (CPU) used in Sony PlayStation 2 video game consoles.

This is how our emotions work:

While the Emotion Engine is now getting on in years, most PlayStation 3s apparently still use it for backwards compatibility. Unfortunately, Wikipedia notes, PlayStation 3 units that use PAL color-encoding — those sold in Europe (but not France) and most of Asia, for instance — "do not include an Emotion Engine as a matter of cost-saving." They rely on "emulation" instead. But these units are in fact ahead of their time: "It is believed that eventually a hardware revision of NTSC units [ones using the color-encoding standard that prevails in North America] will remove the Emotion Engine chip in these territories." It's only a matter of time.
