I'm doing some research on video games and education, and I'm finding a lot of papers make reference to an acronym I haven't encountered much: ARG, which stands for alternate reality game. In the paper I'm currently reading, it is often used in educational settings to teach second languages, for example.
Are RPGs (role playing games) and ARGs (alternate reality games) considered more or less equivalent, or are they actually quite distinct? I'm not seeing any mention of RPGs in these papers, and I'm wondering if the different acronym is because of the academic context rather than a consumerist/marketing context.
(I'm really not sure if this question belongs on this forum, if it doesn't, let me know and I'll take this elsewhere. Thank you so much!)
