Geek of the North
Are there actually big fantasy systems with long rulebooks in the vein of Alliance, Labyrinthe, or NERO somewhere in the Nordic countries? I know they do not exist in my neck of the woods. To me, those are the big difference between what goes on in here vs. what happens across the pond (or in the UK, for that matter). While blockbuster larps have their design documents, they're more about the creative vision and safety than spell lists and character sheets.You're right. Kinda.
I think the main issue is that we're talking about this concept of Nordic LARP contra American.
That's actually faulty. Nordic LARP is... A style. Like Nordic-style Drama. I think the reason it was coined as being "Nordic" is the development of said style in the Nordic countries, whereas a lot of the stuff there is done in Fantasy LARPing in these countries are often more of the same stylistic choices that can be found in Europe and America.
There's a lot of evolution on the topic, and as LARP-cultures are cross influencing each other, we might need to re brand a lot of things.
I do know there are some WoD campaigns going on here and there but I'm unsure how many of them still use Mind's Eye Theater.
