A positive feedback loop in a game is an event that reinforces a winner of the game. The reward becomes stronger with every win. If a player wins a level and wins a power up, then the power up will increase the chances that player will win the next level. It creates an imbalance in the game. This makes the game too easy, or the player gains too much of an advantage at the start of the game. For example, this loop is very obvious in racing games. In the game Star Wars Racer Revenge, the races were hard to win. The player had nothing to spend their money on to add upgrades to their pod. About half way through the game the player’s pod was faster than the others and the challenge was gone from the game early on.
