Roleplaying is a special hobby. Though it borrows from all the best aspects of a community pastime it also brings together a wide variety of colourful people. Imagination is something that everyone has ordinarily, though fortunately I am unsure regarding psychopaths, and despite this one has an opportunity to express oneself artistically as much as applying oneself deductively to any given scenario. As Mark, one of the Chill players commented, his detective's drawback of impulsiveness is very useful in cutting through a lot of preamble despite the rather adverse consequences; an echo of a distant cousin in chivalry we all know too well.
More specifically one can approach the hobby with a method actor's mindset. A nod to the Larpers here and we do entertain those who like to get out on occasion. Putting aside even the fun of dressing up and sheer effort people can put into costume, a tremendous aspect of live roleplaying draws from historical reference, typified in re-enactments. As much as one can learn about events in school or by watching dramatised histories in motion pictures, there is nothing quite like actualliy smelling the sulphur of gunpowder burning the air or feeling the weight of chain mail on your shoulders whilst breaking camp or indeed gazing hopelessly around a field of dead bodies. It simply can't have been all that different in the past and there are moments when you are there. This is a kind special.
The ability to inject a fair amount of humour into a game also brings people together in special ways. Other than clever plays on words and ironic words in clever plays, jokes are for the most part anecdotal on some level which requires one to imagine a point of view. Abstracting from this in many of the fantastical worlds we inhabit just explodes the farcical possibilities and its not uncommon to forget ones head is on fire during tense negotiations.
And then there are just Very Special People. I shall just attach a couple of photos of our last meet while we played something equivalent to Twister for the inebriated.
