What a bizarre collection of articles! That said, it's definitely a "fun" book. I'm not sure how Romans and Greeks fit in to "Pirates to Darkest Africa," but there's quite a bit in there on them.
Pirates - 20 pages, including terrain and ship building
Romans - 20 pages, including gladiator rules
Conquistadors, Aztecs, etc. - 26 pgs
Darkest Africa - 18 pgs
Greeks - 10 pages
At the price of 3 wargame magazines, I was satisfied with the purchase.
