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.

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

Using game‑theory models to explain real‑world politics, economics, and social behavior. Jiang strips away the abstract math and applies concepts like the prisoner’s dilemma, zero‑sum games, and Nash equilibria to everything from dating to nuclear brinkmanship. The idea is that if you can figure out the “payoff matrix” of any situation, you can predict—and even manipulate—the choices of the players. It’s strategy for geeks who want to rule the world.

“Applied Game Theory explains why the U.S. and China are stuck in an arms race: it’s a classic ‘security dilemma’ where neither side can back down without looking weak. Spoiler: the only winning move is to change the game.”

Social Game Theory

The application of game theory to everyday interpersonal and social dynamics—friendship, reputation, gossip, dating, and office politics. It decodes the unspoken rules and strategies behind why you buy a round of drinks, how gossip spreads, or the subtle dance of a flirtation. It treats social life as a series of iterated games where the payoff is social capital, trust, or mating success.

Example: “Explaining why I always help my neighbor move his couch, my friend used social game theory: ‘It’s an iterated Prisoner’s Dilemma. You cooperate (help) to build trust and reciprocal cooperation. If you defect (refuse), you save an afternoon but lose future help and damage your reputation in our social network. The couch isn’t furniture; it’s a token in a long-term trust game.’”
