My solution to the ever-growing junk tables for Gamma World: Junk Tokens.
Each piece of junk from Gamma World and Famine in Far-Go is laid out on its own 1" x 2" token. Print, affix to heavy cardboard, cut out, and toss into a bowl/bag. Instead of rolling for junk, players simply draw a random tile as necessary.
Includes a blank sheet, so that you can just grab a sharpie and add your own junk as you need it, or you can print on top of this PDF file with your own junk lists.
Instructions:
1) Print at 100%, centered on the page, onto good-quality paper or full-page Label paper (check office stores).
2) Mount on heavy cardboard - matt board from a framing store will do nicely, or the backing cardboard from a pad of lined paper works very well too.
3) Cut off margins - .25" on the long edges, .5" on the short edges.
4) Cut sheets every 2" across and every 1" down.
5) Find a container and start generating junk!
