Console Wars is a new book written by Blake J. Harris and tells the tale of the the battle between Nintendo and Sega in 1980 and 1990. Harris tells us that every bad decision Sega made that resulted in a loss of market share — the ill-advised 32X add-on and the premature launch of the doomed Saturn console among them — was entirely within the purview of Sega’s stubborn parent company. Console Wars does not go into the development of the biggest gaming properties Sega developed.
