You could make it a dating sim. Less drama than in the "Wild Hunt" movie, please.

Generally speaking, we have all kind of LARPs in the sword-and-sorcery scene

- battle LARPS - no story, just hit the participants belonging to the other faction, preferably in formations. This ranges from smug reenactment-quality groups, like Warhammer Fantasy fans in Europe, to groups that retain fantasy-themed clothing the way sports such as tennis have a specific proper attire, like Belegarth society in USA.

- (story-rich) LARPS - these originated with to "let's play D&D but in real life" and some of them even kept the trappings of the original, such as "levels" or "character classes"; some of them drop most of the gamey aspects, becoming more or less like those "chamber" LARPs mentioned by the OP (only in a fantasy setting; though, a Dune LARP could be a thinly-veiled middle-east, for all I know)

The logistics in the designs surrounding games of any substantial proportions must be hellish to coordinate with the playmaking's unpredictability.

More construction companies should take it upon themselves to start looking into erecting things like what those Warhammer dudes were enacting in one video i mulled over. Establish some crude barracks, keeps, bastions, and whatever else a play site could sustain. Gather a crew with cameras, editors, and a designer or two, then put some attendees on the grounds, and you’ve got yourselves the trappings of an amateur production going in no time.
