Land price varies between 17 and 26 bushels of grain per acre.\n\
|

Planting two acres requires one bushel of grain.\n\
|

One person can farm ten acres of land.\n\
|

"\n\

You are the ruler of an ancient Sumerian city-state. I, your Grand\n\
|
||||
Vizier, will assist you during your ten-year reign to govern your _ _{)\n\
|
||||
realm. \\/\\/\n\
|
||||
/|\n\
|
||||
At the beginning of each year, you will plan the employment of your /|\n\
|
||||
city's resources to buy or sell land, allocate land and grain to plant _/_|\n\
|
||||
new crops, and allocate grain to feed your people. Some guidelines:\n\
|
||||
\n\
|
||||
* Land price varies between 17 and 26 bushels of grain per acre.\n\
|
||||
* Planting crops requires one bushel of grain to seed two acres.\n\
|
||||
* One person can farm ten acres of land.\n\
|
||||
* One person needs to eat 20 bushels of grain per year to stay alive.\n\
|
||||
\n\
|
||||
On the planning menu, press one of the bracketed characters to [F]eed\n\
|
||||
your people, [P]lant crops, or [B]uy or [S]ell land. When you are\n\
|
||||
satisfied with the plan, press [E] to execute it. You may also\n\
|
||||
[R]eset the current plan and start over, or [Q]uit the game.\n\
|
||||
\n\
|
||||
When prompted for a numeric value (to buy, sell, or plant land, or\n\
|
||||
allocate grain for food), you may enter an integer value, or an\n\
|
||||
arithmetic expression composed of integers and the operators \"+\", \"-\",\n\
|
||||
\"*\", or \"/\" for addition, subtraction, multiplication, and division.\n\
|
||||
The expression will be evaluated with integer arithmetic in the order\n\
|
||||
the operators appear from left to right, and the value of the\n\
|
||||
expression will be used for your input.\n\
|
||||
\n\
|
||||
After the year's plan has been executed, I will report to you the\n\
|
||||
year's events, harvest, births and immigration, and deaths from\n\
|
||||
starvation and plague, and the results.\n\
|
||||
\n\
|
||||
At the end of your reign, history will judge you based on the average\n\
|
||||
portion of the population you starved, and your city's growth in land\n\
|
||||
per person. If in any year you starve more than 45 percent of the\n\
|
||||
population, the survivors will rise up and depose you immediately.\n\

||||
