This is a large six-player map, split to three-on-three with a Hijaz there. There are enough resources on near you, but remember for many mouths to feed. So, a Market is a big solution for your castle.
If you are a beginner, try to select one or many easy enemies or unfamiliar enemies with no-foods and not produce an ale, example "The Rat", "The Snake", "The Pig", "King Phillip", many more...(recomended).
If you are familiar with desert area, try fooling many strong king, example "The Wolf", "Saladin", etc...
