As gamers we have done the western with laser pistols, six shooters and steam tech.  Shadow run alone has covered more noir ground than MGM did between 1945 and 1955. I hope we managed the horror genre well, and the murder mystery almost always sneaks its way into our campaigns. But do we always know we are doing it?  Can genre sit right in front of us an yet go undefined?  I think it has happened and a speculative fiction genre of all things.

Larping is Live Action Role Playing. Instead of sitting around a table, play is done “in action”, up and moving about. Any resolution besides social ones are done by some “lite” mechanic. It can be a great deal of fun.

A standard roleplaying environment: the tavern. This is another easy one to create in your own home, providing you have a large enough group of roleplaying friends. Let us assume your PC group is no larger than five, and that the rest of your friends can be NPCs. Let us also aim for an exceptionally seedy and unscrupulous city tavern.

In a good LARP it is desirable to separate the players out individually at some stage, because they are more suggestible and afraid when they are alone. Some form of individual challenge is probably the best way of doing this. One possible setting for this is a cave system, and it is probably one of the easiest to recreate realistically, and one of the most perfect for playing on fears of claustrophobia and darkness.
