Every game is different. We've got a few standard formats like Apocalypse Games and Citydash, but even those are evolving. When you signup for a game you'll get a quick briefing by email for that particular game.
We do have some more general rules. Although they're more like guidelines..
- Play it the way that's the most fun - for everyone else. You're building an experience as well as enjoying one. If you see an opportunity to make a cool story for someone else, do it!
- Play for stories, not points. Be big, be loud, be dramatic. If you want to rush across a zombie-infested courtyard waving a Vulcan over your head and screaming "LEEEEROOOYY..", do it! It'll be gloriously successful or gloriously suicidal, but either way it'll be glorious.
- Play ^fairly safe. None of our games involve deliberate contact beyond a light touch. But we're often in the dark, so take responsibility for your safety, and don't run into anything, or under any buses..
- We start in the pub and we finish in the pub.
