it's a kind of misrepresentation. The gamers here are not indicative of the typical gamer. Not all gamers are financially unstable, failures, unemployed, or mentally ill. Millions of people play some sort of role-playing game. These portrayed here may be a little more extreme than others, but did you see that they were not the only ones in the LARPs? There were hundreds or even thousands of other players there too. I am sure most of them are respectable people with stable jobs and home lives, who just happen to have the hobby of live action role-playing. Nothing to do with mental illness. Nor did I think those in the film were mentally ill. It's just "normal" people placing stereotypes.
