A Literature Review for Non-player Character Existence in Educational Game

Educational games have a critical role in children not only for entertainment but also for education. Unfortunately, they are not accessible, although educational games can improve student’s knowledge. This paper addresses a systematic literature review on the existing research to identify and classify information about the educational game. The automatic query searches found a total of 892 papers in the digital database from 2015 until 2018, and only 87 papers selected as a quality assessment review. From 87 reviewed papers, only 18 papers fulfilled the quality assessment. The results show that the most common reason why the educational game is not accessible because it does not have a non-player character (NPC). Furthermore, the review indicates information about the game trend and suggestion about the game element for making an educational game. Besides having an educational element, we concluded that the educational game should also have NPC on the gameplay to be more interested.
