How in the hell did I miss this thread? I don't understand half of it, I'm still only halfway.
To answer the OP: thinking about it, probably the fact that Nintendo created their biggest competitor after backing out of a deal of Sony, and said competitor kicked the original Nintendo sworn enemy of the game and made Sega go software only with their second console, which is the biggest platform of all time sales-wise. Oh, and that in turn created a new competitor who loves the letter X to the bone.
Pretty crazy when you think about it.
