SPI Died for Your Sins - this rather gloomy article is valuable for an excellent brief history of hex-wargames.

It is hard for those of us who grew up with wargames, who loved them, who spent so many years studying them and taking them seriously as works of scholarship and art, it is hard for us to acknowledge this. We keep on hoping for some last minute reprieve, some renaissance; how could so much effort, so much inspired work, go for nought? How can it be that all of our labors will be forgotten?

Well take a look at GMT - the renaissance is here.
