ORIGINAL: Matti Kuokkanen
Wargames didn't have manuals like that. They were usually softcover, black and white or with 6 colours or so and less than 150 pages long.
Usually the only full colour parts were book cover, map and game catalogue.
That's BattleTech Master Rules you're talking about. Totally obsolete now. New basic core rulebook for that game now is Total Warfare with over 300 pages, all coloured. I paid 45 € for that.
Newest Warhammer 40k rulebook has 435 pages for 60 €
Rules for expensive miniature wargames are a completely different cup for tea than manuals for computer wargames.

Without social solidarity manifested in the form of welfare state, people inhabiting one territory are a non-nation of mortal enemies engaged in competition for survival.
