When new educational games are developed for teaching languages, a set of ideas or intuitions about how students can gain more knowledge are used; however, few of them are based on a solid theory or substantiated with linguistic research. This chapter presents a brief review about second language acquisition theories; describes the importance of recovering, maintaining, and transmitting indigenous languages; and analyzes efforts made for enhancing bilingual education. Serious games are presented as an alternative for learning indigenous languages, and guidelines to develop serious games implementing second language acquisition theories are proposed. Finally, a discussion about challenges and future trends in recovering, maintaining, and transmitting indigenous languages is presented.
