Conflict arises in games from players trying to achieve goals within the rules and boundaries of the game. Game designers intentionally create conflict by making the rules inefficient and preventing direct accomplishment of goals. Conflict results from challenging players with skills, creating a sense of competition among players, and forcing players to employ inefficient means to motivate continued participation. Common sources of conflict include other players as opponents, obstacles that must be overcome, and dilemmas that require strategic choices between options.
