I love live action role playing, have you tried it? 
No but it does seem interesting. I remember seeing it in a film that I loved. 
What film was that, do you remember? The activity is known for short as (LARP) its a form of a role-playing game where the participants physically portray there characters. 
It was a comedy film that sort of pokes fun at it but ultimately becomes an essential part of the plot. The film was called Role Models. 
I remember watching that as a kid, it was such a good film! The players pursue goals within a fictional setting while interacting with each other
