Over the last few decades, the popularity of video games has skyrocketed thanks in part to their unique ability to engage their audience and to create empathy. Among them, serious games have an additional purpose beyond entertainment; to teach and help people. Serious games have been successfully applied in a variety of different fields, such as: education, health, tourism and also in bringing knowledge about cultural heritage. In this context, this thesis describes a serious game designed to promote Brazilian cultural heritage and  increase interest in tourism. The objective of this serious game was to involve the player in an interactive virtual exploration of Brazil, in order to teach more about its rich cultures and history. Our results show that the  majority of people learned something new about Brazil and became interested in traveling to Brazil, even  people familiar with Brazil.
