Watched this last night. Pretty dang good. It went into depth on the 16-bit war, getting interviews with the people on the frontlines such as Tom Kalinske, Howard Phillips, and others.
The first half is the console war from Sega's perspective, and the 2nd half from Nintendo's perspective. Which is a really cool way to approach it. It's not biased, yet at the same time you hear both side's bias.
Sega of America really seems like the underdog fighting against the evil empire, that some how overcomes them despite the odds. Only to fail because of their own in-fighting coming from Sega of Japan. And Nintendo comes off as the miracle-maker that saved gaming in the 80s to grow into the powerhouse it became.
Well worth a watch. Very interesting stuff, and much more in-depth than the stuff you usually see on YouTube about the subject.
