I take issue with the idea that only JRPGs had complex stories in the 8/16bit days. Even in Japan, adventure games were HUGE in the 1980s and early 1990s... remember Famicom Detective Club? Snatcher?
Also strategy games, like Koei's ROTK series, had really complex (and historically accurate!) narratives. Then there were also genre crossovers like SRPGs (Fire Emblem) or ARPGs (Zelda, Ys, etc).
