CH #1. Back before CH was the CH of today. Got my copy from Rob Wolkey at an early ASLOK shortly after they first came out. Can't remember how much I paid for it, but it was well worth every penny. I read it cover to cover before the weekend was over. That, Fire For Effect, ASL News, the early ASLUG issues, and the first 2 issues of Backblast were very early TPP acquisitions that I probably still have somewhere. Probably a bit smoke stained as they survived a house fire.
I think Wolkey put FFE together - it was kind of a tourney newsletter with tactical articles (no scenarios) IIRC.
ASLUG was Fort's newsletter, with scenarios and great insights from him about his designs or other scenarios. I recall a good piece written by Gary about Bread Factory #2 from RB. My favorite ASL article types have always been scenario analysis such as Fort, Mark Nixon, and others wrote. Applied tactical theory. Great learning tool.
Backblast was put out by the guys who would later become MMP. Some great articles and scenarios in the 2 issues I have. I first ventured into Night scenarios with help from a couple of those articles.
