During the medieval goings-on around Orléans, you must gather a following of farmers, merchants, knights, monks, etc. to gain supremacy through trade, construction and science in medieval France.
In Orléans, you recruit followers and put them to work to make use of their abilities. Farmers and Boatmen supply you with goods and money; Knights will expand your scope of action and secure your mercantile expeditions; Craftsmen construct trading stations and tools to facilitate work; Scholars will make progress in science; Traders open up additional locations for you to use your followers; and last but not least, it cannot hurt to get active in monasteries since with Monks on your side you are much less likely to fall prey to fate.
You always want to take more actions than possible, and there are many paths to victory. The challenge is to use all elements as best as possible with regard to your strategy.
