Terra Mystica is a game with very little luck that rewards strategic planning. Each player governs one of the 14 groups. With subtlety and craft, the player must attempt to rule as great an area as possible and to develop that group's skills. There are also four religious cults in which you can progress. To do all that, each group has special skills and abilities. Taking turns, the players execute their actions on the resources they have at their disposal. Different buildings allow players to develop different resources. Dwellings allow for more workers. Trading houses allow players to make money. Strongholds unlock a group's special ability, and temples allow you to develop religion and your terraforming and seafaring skills.
