"You see, once you have changed the game, you have won a different game entirely." This statement is far from being obviously true. It depends on how we determine what constitutes "the same game". Like there was Godfather game where many players just couldn't win because there was game sequence with racing and this racing was very very hard, so developers rolled out update allowing to just skip the racing part. Did the players buy one game and win different game? It's debatable, despite one version being straight up unwinnable for some players.
