The city of Ashkelon, on the eastern end of the Mediterranean Sea, is one of the major cities of the Philistines. A powerful merchant family (known henceforth as The Family) of this city has to decide how to allocate its vast but finite resources to further their own wealth and the glory and influence of their state. Some trade routes use camel caravans and go to the southern deserts, where they may trade in salt and gold with the great inland African nations; others may go north and west, oversea by galley, toward the Greeks; others may push their foul-mouthed, humped mounts east, overland toward Sumeria, to trade in spices and the crafted goods specific to that region. Some of the routes are over more arduous terrain than others, so make take longer to pay off (no revenue is realized by The Family until the caravan returns to Ashkelon). The financial costs and returns of each route are as follows (in Phils, the currency of the Philistines):

Route	Cost, Period	Revenue, Period 1	Revenue, Period 2	Revenue, Period 3
African	-75,000	215,000
Greek	-50,000		140,000
Summerian	-125,000			385,000
