Conflict emerges through procedures and rules in the game that prevent a player from achieving their goal. Three types of conflicts are common in games:

• Obstacles - physical or mental items that are preventing player from completing the objective.
• Opponents - other player or system players that may harm player.
• Dilemmas - complex choices which consequences are important for the game outcome.

Boundaries the game system limitations that describe the end of a gameworld, or the maximum or levels that could be reached. They also define the border between game and real life.

Outcome is something that happens at the end of the game where player is winning. The outcome is not precisely defined for the players and has to keep them intrigued to continue playing to find out what is waiting for them.
