It's perhaps about time I talked about this book, written by Ian Livingstone with illustrations by Russ Nicholson, which was published originally in 1982, but didn't cross my path until '86 or '87. It also might have been redundant, given that I was already familiar with role-playing games, but this was bought during a period of my life when information was a lot harder to find than it is now, and I was really intrigued by the fact that here was an entire book on the topic.
STARFIRE was Task Force Games big spacefleet battle game. I never have played or read the rules, but it has/had a very loyal following. You run across it a lot when you search for Star Fleet battles stuff, being the same publisher and all.
