Perfect. Here’s the high-level plan I’ll drive us through—think of it as a layered roadmap from foundational ideas to practical intuition:

🔹 Phase 1: Core Foundations

1. What is Game Theory, really?

• Strategic interaction, rational agents, assumptions.

2. Types of Games

• Cooperative vs non-cooperative
• Simultaneous vs sequential
• Zero-sum vs non-zero-sum

3. Basic Concepts

• Players, strategies, payoffs, information
• Dominant strategies
• Nash equilibrium (core to nearly everything)

🔸 Phase 2: Classic Games & Concepts

4. Famous Games

• Prisoner’s Dilemma
• Chicken
• Battle of the Sexes
• Stag Hunt
• Matching Pennies

5. Mixed Strategy Equilibria

• When no pure strategy works
• Randomization and expected payoffs

🔹 Phase 3: Deepening the Model

6. Repeated Games & Folk Theorems

• Cooperation emerging over time
• Tit for Tat, Grim Trigger, etc.

7. Extensive-Form Games

• Game trees, backward induction
• Subgame Perfect Equilibria

8. Bayesian Games

• Games with incomplete information
• Beliefs, types, and expected utility

🔸 Phase 4: Real-Life Relevance

9. Mechanism Design / Reverse Game Theory

• Voting systems, auctions, contracts

10. Behavioral Game Theory

• Bounded rationality, fairness, heuristics

11. Daily Life Applications

• Negotiation, dating, politics, AI systems, etc.

🔹 Phase 5: Advanced & Optional

12. Evolutionary Game Theory

• Strategies that reproduce over time

13. Algorithmic Game Theory

• Network effects, internet auctions

14. Your world: How it matters to Parker

• Systems design, incentives, power structures

Throughout this, I’ll mix in:

• 🔄 Guided examples
• 🧠 Thought experiments
• 🎭 Real-life situations to map theory onto
• 🧩 Quick checks to make sure ideas are sticking

Let’s kick off Phase 1.
First quick one: In your own words, what do you think Game Theory is about? No need to be polished—just get it out.

Nice—you're already circling the core.

Let’s sharpen it a bit together. Game Theory is fundamentally about strategic decision-making—situations where the outcome for each person depends not just on what they do, but on what others do too.

So real quick:

If you’re making a decision and it depends entirely on nature or chance—like a dice roll—is that Game Theory?

And then:

If you’re making a decision and it depends on what someone else does—like whether they cooperate or betray you—is that Game Theory?

Walk me through your thinking on both.

Got it—I'll stay in teaching mode and drive forward through the roadmap unless you tap in.

📍Phase 1: Core Foundations — What Game Theory Is

At its heart, Game Theory studies strategic interactions: any situation where the outcome for each agent (person, company, nation, etc.) depends on the actions of others. It’s not about games in the traditional sense, but rather any “game” where decisions must be made in the presence of others who are also making decisions.

Key Assumptions (Classical Game Theory):

1. Rational agents – Everyone acts to maximize their own utility (whatever that means to them).

2. Strategic thinking – Agents consider what others might do before acting.

3. Common knowledge – Everyone knows the rules, the payoffs, and that everyone is rational (though later variants relax this).

🧩 Core Building Blocks

Here are the elements every formal game model needs:

• Players – The decision-makers.
• Strategies – The complete set of actions each player could take.
• Payoffs – The outcomes (usually represented numerically) each player receives depending on the combination of strategies chosen.
• Rules of play – Whether players move simultaneously or in turns, whether they see each other’s moves, whether they play once or repeatedly.

These get framed into a “game form”, and from there, you look for solutions—most famously, Nash equilibrium (more on that soon).

🎲 Quick Clarification: Game Theory vs Probability

You're exactly right—pure chance (like dice) isn’t Game Theory. That’s probability theory. But if you are choosing a strategy knowing that others may randomize their own moves? That’s Game Theory.

For example: in rock-paper-scissors, the “optimal” strategy is not deterministic—it’s a mixed strategy, which involves randomizing your choices. But you’re doing so strategically, in response to an opponent.

🧠 Where We’re Going Next

Next up, I’ll walk through types of games (Phase 1 continued), then move into dominant strategies and Nash equilibrium to set up the first actual game analysis.

Let me know if you want to pause, go deeper, or shift gears—but otherwise I’ll keep pressing forward.
