I've talked about how character creation has slowed down my games more than once. Fast packs are a great first aid for this...A pre-made set of items to get the players into action with their characters more quickly.
I first saw them in TSR's B4 module "The Lost City" (pictured above). Al's "Starting Equipment Package" at his blog Beyond the Black Gate is the most imaginative use of fast packs I've seen, coming as they do with a proper back story/setting. Very cool! I'm not sure how the item costs correspond with LL/S&W, but Microlite20's site also has a PDF of fast packs.
I'll have to whip some of these up, with a proper back story at some point. They're just too handy and often used to not have readily available, and the possibility of a plot hook or twist is hard to pass up.
