The only thing that sets the Villagers apart are their clothing, the type of building they reside in, and the type of profession and trade offer they have.
Many of the trading offers are the same as they were when first developed, and all of the Villagers have the same model. However, not much has been done in regards to these villages. Trading was a very interesting feature as well, allowing the player to better manage their resources with the quirky testificates that inhabited these newly introduced villages. The interesting buildings, professions, and locations were loved by many when they first dropped. Villages were a great addition to the game when they first came about.
