I designed a board game with similarities to SimCity and Monopoly. So far, I have playtested with prints from local print shops, which are expensive. I have finalized the design (I'm an amateur graphical artist) and just need to balance numbers but I don't want to spend $50 every time I print out a new board (24x36") and $14 for the cards (Chance, Move, Charity, and Deeds, 13 11x17" pages for 2 decks). I just reuse standard playing dice, cm cubes, and movement tokens every time I play with friends but I need to playtest where none of the players have played my game.
Any suggestions for making affordable prototypes would be appreciated.
