Checkers is a board game that I remember playing and the object is to move the pieces and the properties to the other side of the board and the pieces can be changed into kings by getting to the other side of the board and the kings can move any way they want. You are supposed to take out the opponents checkers by jumping over all of the opponents pieces one at a time to win the game.
Call of Duty is real time because it is player vs. player and it happens at the same time. Methods of control in Call of Duty is that you can determine how to move the player and how to win the game you want it to.
In the board game checkers you move the pieces diagonal but what if you had cards that said to move in a different direction then it would change the balance of the game.
