So, here's my knowledge of the game: At the beginning of time, hundreds of giant hammers, coins, and slices of bread littered the landscape. Your cities produce skilled laborers who harvest these for your benefit. Here's the tick, though: One hammer on a tile means you produce... one hammer. A city that is harvesting five hammers every turn will take 3 turns to produce a unit that requires 15 production. Same with bread. Coins, on the other hand, don't seem to follow this. More coins DOES equal more gold, but only in a vague sense. I can't seem to figure out the actual system. Trade routes likewise; sometimes acquiring a new trade route boosts my gold considerably, other times it has no effect. How the heck does this work? What are the NUMBERS behind it?
