A print-and-play game is a game that can be printed out on your computer onto card stock and then played. It also includes games that can easily be made with common game equipment, such as dice, playing cards, pawns, checkers, etc.
Proxy Wars started as a Print & Play game and developed to a full game production now. This means nothing is needed except a scissors and you even just need it to print on simple stationary – no cardstock needed. You may want to use some chips, meeples or coins instead of the included paper markers as agents, as they provide better usability.
