Happily, many of the games in the book are available as completely free print-and-play PDFs. Several of those require only a board, which is simple enough to print. In other cases, you might have to print cards, boards, etc. (James has created handy reference videos to help you make bespoke print-and-plays.) In true Cheapass Games fashion, you will need to dig up generic parts like dice, pawns, play money, etc.
