The knowledge of a second language is an obligation in educational systems of the European Community for many years and the quality of teaching and learning, especially in Italy, could be largely improved for a better outcome. Methods like Game-based Learning and Gamification could improve and change this outcome, combined with new tools used as educational technology in an immersive context. This paper presents some lessons learned from the adoption of VR / AR within two applications related to language learning. In this context, being immersed in an engaging and fun simulated situation is a good way to practice language conversations. In the last few years the great clamor of new VR / AR devices (HMD, controller, tracker) promotes the creation of new frameworks of extended reality for language learning.
