Dziobak larp studios, producers of College of Wizardry, Fairweather Manor, and assorted other blockbuster larps, has shut down, leaving behind a mountain of debt. There’s a long explanation here, but the TL;DR seems to be be that they kept running games at a loss, then tried to make it up on volume. Which is pretty obviously Not A Good Business Plan.
The good news is that the business model they pioneered - big, expensive, blockbuster larp - is thriving even as they are dying. There’s a number of different producers now, producing large, high-quality, big-budget events. And now that that segment of the market (older larpers with jobs / tourists) has been discovered, it doesn’t look like it will go away.
