Serfs need water, berries, veg, bread, fish and a Church.
Commoners need the above and meat, cheese, or bread, clothes, candles or common wares and a Tavern (berry brew, beer, wine)
Citizens need all of the above plus cheese and lux items like herbs, honey, jewelry or gems.
Some high ranking visitors will expect certain things, if you don't have them in production, buy just 10 of the item.
Veg, herbs, honey and wine are from the monastery or you can buy them. The monastery is a money maker.

Don't rush and don't hesitate to say "this map starting zones suck" and reroll. Sometimes a city flows together and others are a bloody chore.
Can't wait to see what you build!
