This year, the three Swedish larp organizers Frida Gamero, Sofia Stenler and Annica Strand started their blog Arrtankar. There write and reflect on larp organizing, while preparing for upcoming projects. Previously they have made great projects such as Understockholm and Next stop Kymlinge. Arrtankar currently holds a bunch of great reads, and my guess is that they will produce a lot more articles. The blog is in Swedish but you can find a translated link below.
I asked Frida Gamero why hey started Arrtankar:
The blog is about the many different aspects of producing a larp. We started the blog to show how all the parts of fiction, creativity, communication and practicalities come together to form a larp thats is ready for the participants to take part in. By writing about how we work we hope to inspire and help others in the process to take an idea and create a larp, from start to finish.
