The focus of the article is on data-self technology in digital entertainment - virtual entities that replicate and/or are influenced by players’ behaviors and actions, working as agential mirrors on the screen. Little efforts have been done in investigating their potential in social research and educational technology; however, data-selves can serve as promising self-revealing tools toward personal identities and narrations. In order to enlighten their effectiveness, a multidisciplinary framework led by the core concepts of “narrative identity” and “discursive-practical consciousness” is advanced. The proposal has been tested (pre-post interviews and play sessions) with an empirical exploration involving n:32 participants and the video games Black and White 2 and Forza: Motorsprint 5, which include data-self features. Results show that this technology can make a difference in engaging and stimulating subjects’ interest and feedback, but further researches are needed to deepen its scope and range of application.
