If they player can operate in only one field, there is a chance that he will become stuck or fall very far behind.

There should be more than one path to the goal, be it a ClearShortTermGoal or a long-term CompellingGoal. (Well, short term goals should be compelling too.) This can be especially relevant in preventing the player from getting stuck in a OnePlayerGame, but can be just as useful if another player is dominating one field of the game.

Called "Provide Parallel Challenges with Mutual Assistance" in Better_By_Design?, April 2002. "Mutual assistance" is essentially PositiveFeedback, but it is especially relevant here. If a player is stuck on one challenge, completing others should make him better able to confront it.


Therefore, provide more than one way for a player to achieve goals and victories.
