Seen from the US: Dammerung, a Norse fantasy / climate change larp. It’s interesting because its an example of a US larp that is mechanics-light (in fact, we’d find the character creation and mechanics perfectly normal here), and its novel approach to power creep (games set 25 years apart, so no expectation of character continuation or survival beyond one or two episodes).
