This literature review summarizes research on game-based learning based on the categories of research outcomes. The analysis include total of 25 research papers that are published in this decade. They are categorized into four parts: cognitive aspect, affective aspect, psychomotor skill aspect, and behavior. In spite of cross-aspect of each research, we found that more researches focus on the impact of games on cognitive and affective aspects as well as the observation on related behaviors, and less on psychomotor skill aspects. Continued study is needed to provide in-depth qualitative analysis on the theories, methods, and results of these researches, which conclusion might direct us to future trends of game-based learning researches.
