Create a Tic Tac Toe Game & Learn About Event Sourcing

🎮 Create a Tic Tac Toe Game & Learn About Event Sourcing – Build Smarter Systems Through Simple Play 🧠⚡

What if building a simple game could teach you a powerful backend pattern? In this hands-on session, we’ll use a classic Tic Tac Toe game to introduce Event Sourcing — an architectural approach where every state change is captured as an event.

You'll build the game step-by-step, then explore how to store and replay every move using event streams. This session is perfect for developers curious about Domain-Driven Design, CQRS, and event-driven systems, all while having some fun!

🎓 What You’ll Learn
🎯 What is Event Sourcing? – Understand the core principles and when to use it
🎮 Modeling Game State with Events – Each move becomes part of the system's history
📦 Storing & Replaying Events – Learn how to rebuild game state from an event log
🛠️ CQRS in Action – Separate commands and queries for better design
⚙️ Event Versioning – What happens when your events evolve over time
🔍 Debug with Confidence – Use event history for tracing and analytics
🌩️ Scaling the Pattern – How this idea applies beyond games (finance, IoT, SaaS)

🧰 Tech Stack: .NET / C# | EventStore / SQL / Custom In-Memory Store
