1 Re-Imagining the Sibling Rivalry Narrative in Ibong Adarna Beatrice Margarita V. Lapa, PhD Abstract Almost all high schools require the reading of Jose de la Cruz’s “Korrido and Life Lived by the Three Princes, Children of King Fernando and Queen Valeriana in the Kingdom of Berbanya”, more popularly known as “Ibong Adarna”. The story seems to promote, however, family values that are rife with jealousy and betrayal, as shown in how the protagonists’ older brothers violently turn on him when he just effectively rescued them from certain doom. This paper describes a video game project, Adarna, as it re-imagines Filipino sibling rivalry that evolves from intense competition to brotherly coopetition. The project aims to be a point of discussion in universities and colleges’ game development classes, in particular those that involve the study of the socio-cultural impact of games. Keywords: Philippine literature, culture, games, family 1.0 Project Background Figure 1: The protagonist Don Juan, as illustrated by Eunice Gatdula, on one of the loading screens.
