War videogames raise a lot of controversy in the educational field and are by far the most played videogames worldwide. This study explores the factors that encouraged gamers to choose war videogames with a sample of 387 Call of Duty players. The motivational factors were pinpointed using a non-experimental descriptive exploratory study through an online Likert-type survey that was valid and reliable (Cronbach’s α = 0.897, Kaiser-Meyer-Olkin coefficient, KMO: 0.903). A factor analysis with varimax rotation was applied, which yielded 7 dimensions: graphics/playability; social interaction; learning; challenge/overcoming; fantasy; fun; and competition. Considering the score obtained for each dimension, it can be concluded that the most influential motivational factors were game graphics/playability game and the social interaction allowed by its multiplayer online status, both of them being factors determined by game design elements. These aspects should be considered in the design of educational activities so as to make them impactful and motivational.
