Any kid who grew up in the 80's - 90's has know the classics. Operation, Shoots and Ladders, Perfection, Battleship... but above them all - the Risk board game.
The Risk Board Game
If you can play the game of Risk, I may not want to play you in Chess. And really - That's the highest praise you can bestow on a board-gamer. That's not even an opinion, that's just science. If you can find a Risk board game at your local toys-r-us, I'd certainly suggest picking one up.
