I just came back from a LARP con. Swedish LARPs tend to be pretty artsy, with a lot of emphasis on identifying with your character, while realistic-looking equipment and environments are not as important.
For example, one of the mini-LARPs I took part in had the backstory of Sweden getting nuked, and sixteen people in a bus survive, miles from civilisation. Then it got Lord of the Fliesy from there. It was awesome. Especially because when you died, you would remain as a 'shadow' and whisper things into the ears of the living, representing their subconscious thoughts.
Remus: Harry... I'm a werewolf.
Harry: Are you fucking serious?
Remus: Well yes, but I don't see how that applies here.
