Why is game theory translated into game theory?

I understand your question like this: Why isn't game theory called game theory? Or why is game theory called game theory? (No other name)

First of all, the game is the meaning of the game, but its meaning is not limited to this. It also means competition, such as football match, chess match and so on.

Secondly, the research object of game theory is the participants of the game, and its research content includes the optimal strategy of the participants and the equilibrium of the strategies (Nash equilibrium). ), as well as the definition of game rules (mechanism design) and so on. In a narrow sense, taking chess as an example, game theory can study the best strategy for both sides to win the game. It can also study the winning strategy of any "game" in practice. However, scientific research is by no means limited to this. Game theory not only considers the narrow game, but also covers a "competition model".

Third, people naturally think that chess is a game, and video games are also games. So gambling between two people is a game? A game between hackers and security experts? A game between police and prisoners? A game between buyers and sellers? These all contain conflicting relationships, so in a broad sense, they all belong to the category of game.

Fourth, the (narrow) meaning of game in game theory is "playing chess". But in life, the meaning of these two words goes far beyond this. It vividly depicts the relationship between competition and conflict among participants. So I think it is very vivid and accurate to translate game theory into game theory.
