I agree with what he said above. There are several things you could do.
1. Purchase the board for play testers and have it shipped to them. This gets expensive, but allows you to have the game play tested. This would probably limit the number of test plays. 2. have print files for the entire board. Having people print and cut out everything is very time consuming, so I'd make it as easy as possible. 3. Give play testers a free copy of the game and stretch goals upon completion of a successful KS campaign.
We used Magic the Gathering's board game for most of our initial testing and didn't know if it would be asking too much from play testers to purchase that game for $10-15 on Amazon in order to test our game?
