Game Breaker/Video Games/Party Game

Examples of Game Breakers in Party Games include:

The NES version of Monopoly allows the player to make offers on AI players' property, which the AI will accept a certain percent of the time depending on how high the offer is. However, since there's no limit to how many times an offer can be made per turn, the player can repeatedly offer an extremely low amount for a property and the AI will eventually agree. Effectively, this means the player can take over the entire board with ease.
