Commands & Colors: Medieval is based on the Commands & Colors game system and by design is not overly complex. The Medieval game introduces many new game concepts to the Commands & Colors system, which add historical depth and flavor. Some of the new concepts are:
- Superior armor and status when battling
- Cavalry units increase to 4 blocks
- Heavy infantry battle dice are reduced from 5 dice down to 4
- Light Bow Cavalry units can employ the Parthian Shot when they evade
