Game Theory 

Game theory is something that people can use when in a competitive scenario during gameplay. It is also used during war, and business, because it solves problems based on psychology!

*Playing Among Us (a very famous game)*
"I have to use game theory during the game or I could lose!!" Said y/n.

Game Theory Bait 

AKA Theorybait; is a type of video game (usually in the indie horror genre) with a ton of overcomplicated and contrived lore that doesn't need to be there, these games are usually made only to get attention from big YouTubers like Game Theory or Markiplier.

game theory bait includes games like fnaf, batm, hn

these games become especially clear with tweets from devs like

I believe @MatpatGT is really going to enjoy this 👀

The Roast Game Theory 

1. The theory of who the child is, when he or she was born, and when he or she was slaughtered and eaten as a "Christmas Roast" for not believing in Christmas. It's a theory based on the fact that families literally ate their own children as their "Christmas Roast" after slaughtering them for not believing in Christmas from 1998 to the summer of 2017.

2. A catalogue series on YouTube, Bitchute, and Archive.org to show evidence of where the child was slaughtered by obvious blood stains, even before that, it was based on the smell of inside the house, because humans like children, smell like a dead pig.

Just like Darwin's Theory of Evolution, The Roast Game Theory is a plausible theory.
Just like Evolution is a fact, The Roast Game is a fact too.

But that's just a theory, a Game Theory! 

Most commonly used by MatPat, owner of the Game, Food, Film and Style Theory channels.

Used at the end of videos to remind people that he is just making theories and might not correct.

Applied Game Theory

The use of game theory’s mathematical models—which analyze strategic interactions between rational decision-makers—to solve real-world problems in economics, business, politics, and biology. It moves beyond the textbook “Prisoner’s Dilemma” to design auctions, negotiate treaties, price products, or even schedule airport security checks. Practitioners don’t just predict what players will do; they design the rules of the “game” itself to incentivize better outcomes, like creating a market that naturally reduces pollution or a contract that aligns an employee’s interests with the company’s.

Example: “The city used applied game theory to fix traffic. Instead of just adding lights, they made each traffic signal an ‘agent’ in a game, rewarded for keeping cars moving on its road but penalized for creating gridlock on intersecting streets. The signals started cooperating, learning to form ‘green waves.’ They didn’t just react to traffic; they played a city-sized game of optimization and won.”

Historical Game Theory

The analytical approach of using game theory to model and understand the strategic decisions of historical actors—kings, generals, diplomats, revolutionaries. It asks: given their information, incentives, and the likely actions of their rivals, was going to war, signing a treaty, or betraying an ally a “rational” move? This doesn’t reduce history to math, but provides a sharp lens to cut through narrative and see the cold, strategic calculus behind pivotal moments.

Example: “A historical game theory analysis of the Cuban Missile Crisis frames it not as a moral showdown, but as a brutal game of ‘Chicken’ between Kennedy and Khrushchev. Each move—the blockade, the secret deal to remove missiles from Turkey—was a strategic play to force the other to swerve (back down) without triggering mutual annihilation. It shows how they rationally danced on the edge of an irrational abyss.”
