Risk Legacy

Competitive legacy board game designed by Rob Daviau and Chris Dupuis and published by Hasbro in 2011, generally regarded as the first legacy board game. Built on the rules of Risk, it is played as a 15-game campaign in which players permanently alter the board with stickers, found cities, sign the board after wins, open sealed packets when conditions are met and tear up destroyed cards, leaving each group with a unique copy.
