Academic theory on play, games, and even roleplaying games exists. But there also exists much non-academic work on roleplaying games, including the named theories mentioned in the title, but also (broadly interpreted) discussions of theoretical nature that do not construct a model or classify anything. Examples of the latter are justifications of rules such as getting experience from gold pieces, advice on how to best create immersion, or discussions of stakes setting among story game players or designers.
Does there exist an academic term for these kinds of theories or models in the study of roleplaying games? By "these kinds of theories" I mean theories created by hobbyists in a non-academic context. I am looking for an umbrella term that covers all such theories or all such models.
If the answer is negative, then a generic term for theories created by hobbyists would also be interesting.
As I am interested in academic usage of terms, so please cite and quote academic publications that actually use the term in your answer.
