Console Variations: Most and Least

[Sonicwolf]

I would say the opposite...to me a system with two different casings is more "different" than say, two "variations" of the PlayStation that have different CD speeds. But I think both should be valid for the purposes of this thread.

Those PlayStation variations arent very major though. From eye, its not really easy to tell if one PS plays at a different cd speed. Unlike something with the Genesis where the console was primarily redesigned 2 times.
