Doing the rounds from Medium: An (Australian) look at different types of larp:

One good point about this is that rather than trying to be exclusive (“boffer OR theatre-style”), it recognizes that many of these types overlap. Lots of the stuff we do in NZ is usually “parlour one-shot scripted (political)” or “combat campaign”, though we’ve recently seen some “parlour scripted campaign” larps (Scandal & Society being the big success story there).
Also, it mentions The Innsmouth Papers.
