The objectives of this study were to reproduce a competitive online game based on self-guided presentations and multiple-choice tests in a mandatory format, to evaluate its development and student perceptions compared to a voluntary edition in 2015 (N = 90). In 2016 and 2017, respectively, 191 and 182 third-year medical students participated in the game as a mandatory course activity. The mean (+/- SD) score of the game was 74.7% (+/- 19.5%) in 2015, 71.2% (+/- 21.5%) in 2016, and 67.5% (+/- 21.5%) in 2017 (P %K education research %K e-learning %K computers %K game-based learning %K gross anatomy education %K radiology education %K medical education %K undergraduate education %K virtual worlds %K Self-determination theory %K Health-care %K User acceptance %K Serious games %K Education %K Motivation %K Voluntary %K Elements %K Skills %K Gamification %~
