Abstract
Emotion has become an important part in games. The purpose of this paper is to find whether game elements could influence players emotion? Which elements in a game could evoke player emotions? Previous theories showed game elements could be classified into two layers: the underlying layer and the metaphorical layer. Moreover, aesthetics, narrative, social interaction, and players’ ability in games could be emotional triggers. In this paper, we performed a case study to compare the two versions of a game: Game for Peace and PUBG Mobile. By using NLPIR (Natural Language Processing & Information Retrieval) platform, we analyzed 149 reviews of the new version to estimate the influence of specific game elements on player experience and emotion. Our study showed that: (1) even the small change of game elements has potential to influence players experience and emotion. (2) both the metaphorical layer and the underlying layer play a significant role in evoking players’ emotion. (3) Without the change of core gameplay, the alteration in theme and a metaphorical layer could alter players experience and emotions.
