In 1954, “almost as a lark,” Roberts decided to manufacture and sell the game to the public. It sold only two thousand copies in the next five years, but Roberts saw an untapped market for adult board games and pressed on. In 1958, he designed and published Gettysburg, which simulated the American Civil War battle; it was a hit, and by 1962 Roberts’s Avalon Hill game company was the fourth-largest producer of board games in the United States.
