Porting means adapting a game to run on a platform it was not originally built for. It has become a significant revenue strategy because the development cost of a port is a fraction of building a new game, but the revenue potential can be substantial. The Nintendo Switch became a porting goldmine because its portable nature made players willing to rebuy games they already owned on other platforms. Steam Deck created a similar effect for PC. Porting also extends a game's commercial lifespan well beyond its initial launch window.
