Orléans: Big Box — first released as Orléans: Anniversary Box — collects all released materials as of 2025 for Orléans, a game set in the French city of the same name during medieval times in which you must assemble a following of farmers, merchants, knights, monks, etc to gain supremacy through trade, construction and science in medieval France.

In more detail, you will recruit followers and put them to work to make use of their abilities. Farmers and Boatmen supply you with money and goods; Knights expand your scope of actions and secure your mercantile expeditions; Craftsmen build trading stations and tools to facilitate work; Scholars make progress in science; Traders open up new 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 will always want to take more actions than possible, and there are many paths to victory. The challenge is to combine all elements as best as possible with regard to your strategy.

Orléans: Big Box included three new Ortskarten — that is, place tiles — and those tiles are included in Orléans: Big Box, in addition to being available separately.
