Cloak and Dagger (C&D): the process of revealing as much as possible about another Civilization with various tricks, usually involving the demographics (F11) page. What everything means: approval rating: calculated as (#ofHappyCitizens + .5*#ofContentCitizens + .5*#ofSpecialists)/#ofCitizens GNP: each gold, PRE-CORRUPTION, is one million here. Mfg. goods: each shield, POST-CORRUPTION, is one megaton here. Land area: each square is 100 sq. miles. Includes water territory. Literacy: (#PopsInLibrary Cities + #ofPopsInUniversityCities + #ofPopsInResearchLabCities)/(#ofCitizens*3) -if a city has TGL, Newtons, ToE, SETI, Internet, or Cure for Cancer, it's considered to have all three improvements. Apollo and the Intelligence Agency count as one and a half improvements (for a max of the three, so a single city is never considered to have over 100% literacy). Also there's a 3% bonus when you discover literature. Disease: % of total tiles that are either jungle or floodplains. I believe water tiles are included in the total here as well. Life Expectancy: Just like Literacy, except replace libraries, universities, and research labs with granaries, aqueducts, and hospitals. Can only range from 20 to 99. Family size: (Total amount of excess food being produced)/(2*#ofCities) Military Service: (10 * #ofMilitaryUnits)/#ofCitizens Annual Income: # of connected luxury and strategic resources + 1 for the first trade route w/ another civ. This number can't be zero and starts at 1. Productivity: #ofUncorruptedGold + #ofUnwastedShields + #ofUneatenFood One can infer quite a lot based on this early stuff given our numbers and our rankings that the F11 screen gives us, especially in the early game. We could, as an example, tell that another civilization founds a settler factory on floodplains if we notice one turn that our rank for disease has improved along with a decrease in land area or population or a relative increase in something like life expectancy. This is easier to do in Civ 4 where it gives best, worst, and average rankings (thus you can figure out each civ) but it's still not that difficult to place together a picture of each civ's performance based on turn-by-turn observation. I'd like to translate the other forums to learn some Civ 3 specific methods I may not know, but this is a job I can do for everyone (if y'all would like) as the game begins.
