Ah, if you want to know about how the game works, you should read the Rules.
Two years later, and I find myself on a car journey from Candlestone to Cambridge after a very long day. My friend driving is as tired as I am, and at 11pm the conversation had mostly devolved into making your mom jokes (thanks XKCD and complaining about things we hated. In those sleep deprived moments I made a joke about how if you removed everything I hated from killer, you'd end up with a game about sending people persents, and Nick's comment that "well that would work" led us to have a full ruleset in twenty minutes.
Well, that's more of a lower bound, you're welcome to spend every waking moment playing, but I would at least suggest taking time out to eat and sleep.
Maybe, it's a bit of a trial. I don't expect people to spend more than a pound or so on materials for each gift, which works out at about three pounds a week, which is about the same cost as some university societies.
This is a trial game, I want to see how it goes. One big round would be fun, it'd be like the world's biggest secret santa... but I've done secret santa before, I want to see how this goes.
Scoring was in my old rules, but I decided that the competetive aspect wasn't adding much to the game. Worse, no-one could write proper reports under the old rules until they got three presents, which was holding the game up a lot. With these rules, you don't actually need to wait for the post to start a new round. Hey, if this is successful I'm sure we'll do it again with new rules.
