'game-changing' originates from the combination of 'game' and 'change,' where 'game' refers to a structured form of play or competition, and 'change' means to make or become different.

'game-changing' evolved from the concept of altering the rules or dynamics of a game, eventually becoming a metaphor for significant impact in various contexts.

Initially, it meant altering the rules of a game, but over time it evolved into its current meaning of having a significant impact or effect.
