right now GameSpy has a nice little article going on.
That list is pretty dead on.
Should NeoGeo be on there? Sure it did well as an arcade machine (still making games for it!) but as a console i'd say it was a failure.
I was surprised to see that the Sega Master System wasn't on that list.
They forgot about the PS2
I have owned most of them.
I am a big SMS fan and I still have mine but it when I was growing up it seemed like I was the only kid in town that had one and only a few stores even sold games for it.
Didn't Nintendo get in trouble for telling stores they would pull their products if the stores stocked Sega products?
