Diatribe is relatively independent of NZLARPS, brand-wise. Which is a good thing, because it’s for all larpers (not just society members).
In terms of an initial offering, I’m thinking something like:
For kids:
[ul][li]Knight School[/li]
[li]A Narnia adventure[/li]
[li]A Harry Potter adventure[/li][/ul]
For adults:
[ul][li]Battle Games[/li]
[li]A Dead Man’s Chest[/li]
[li]perhaps another Freeform Games scenario, like Curse of the Pharaoh?[/li][/ul]
I can picture how all of these could be run in a backyard. All of them except the kid’s adventures could be run with just one GM. The kid’s adventures are the only bits that need some writing, and that’s something I’d be glad to work on. Having just watched and loved Voyage of the Dawn Treader (preferred it to the last two), I’m having a bit of a Narnia fixation and re-reading the books at the moment. In terms of Harry Potter, I’m picturing a scenario where something magical is happening in their backyard, and a bunch of wizards and magic folk turn up to try to deal with it, and these wizards need the kid’s help (perhaps because they’re also dealing with stuff happening elsewhere at the same time). The kids play themselves, but could “learn” magic to use during the scenario.
While the kids’ adventures would need more NPCs, I think they’d also be shorter. An hour of play time is probably enough, otherwise you may lose their attention. Shorter time = smaller payment per NPC, keeping it affordable for a kids’ party.
I think several of these games would require (or at least benefit from) some nice swords/shields/etc because that gear is great fun to play with and the looks impress young and old. (No, I’m not just trying to sell more stuff). The most gear would be required for Knight School and Battle Games, because those would be all about the fighting.
