When starting out or building a new city, you should build an inn and feasting hall ASAP. Feasting Halls allow you to appoint a hero as a mayor. Based on the stats of the mayor your town may produce, more resources, build armies faster, or do faster research at the academy. Building your buildings faster and gathering resources faster can allow you to get a fast start!
