This is my Fiasco grab bag (index cards, a black sharpie, dice, and a playset or two or twelve). If I'm in a hurry and I don't know what exactly I'm going to get up to at my destination, I can grab it and throw it in my bag. Fiasco's rules are light enough to remember easily, and if I want to have the complete package I can include the playmat and cheatsheet in the bag. I've also done this for In a Wicked Age and Shock:. And Ghost/Echo, but that sort of started out in a ready-to-go format. I just had to laminate it.
Do you guys have anything like this? In a Wicked Age makes for a great go-to boredom reliever (just add... people!). I can see other games working well, too, like Lady Blackbird or even Apocalypse World (hacked correctly, of course).
What sort of ready-to-go, gaming emergency kits have you guys made? Pictures if you have them!
