As such, it is a metaphorical representation of the fundamental ideology of the United States; the past is no constraint on the future, and each individual should strive resolutely for personal advance despite whatever the past may hold. The child born in a log cabin may achieve the presidency, an immigrant boy who grows up in the slums of Brooklyn may become a real-estate magnate, an Ivy-educated scion of wealth may wind up on a bread line, and a double green will speed you to the fore. Though there are winners and losers, initial conditions are no determinant of outcome in the freedom of America.
Tom Armitage references both Johnson and Costikyan in his response, Taking Turns.
Candyland is a great first game; literally, the very first. It teaches turn-taking. It teaches the mores, the manners, the culture of playing boardgames. Later, when a child comes to a game where the rules are more complex, the turn process more intricate, the customs of gameplay are already learned; rather than focusing on learning the social interactions, they can focus on the complexity of the game itself.
