 This paper examined the use of mobile serious games, MSGs, as a way to study the relationship between emotions and decision making in socio-economic contexts. MSGs combine multiple socio-economic interactions into one narrative, allowing users to experience different emotional states while playing. The authors conducted an initial experiment with eight participants using a mobile serious game to measure the effectiveness of MSGs in the wild. Results showed that the MSG was effective at eliciting emotions and producing similar results to those seen in controlled experiments. The authors concluded that MSGs could be used to study the relationship between emotions and decision making in socio-economic contexts in the wild, expanding the reach of these methods beyond laboratory settings.
