This is a lecture for those who want to consistently write a technical blog. Starting is easy, but trying to do it consistently leads to many trials and errors.

It contains all my 7 years of experience, including SEO, technical blog writing strategies, writing process, etc.

I have produced nearly 30 advertising videos using AI, sharing the prompts and production processes along the way. However, the question I received most often was surprisingly this: “What was your thought process behind creating this?” AI capabilities are advancing by the day. Yet, there is an essential element required to utilize that technology properly: the ability for independent thinking—to set your own standards and make your own judgments. AI truly functions as a tool only when your own perspective and criteria for judgment are firmly established. The goal of this lecture lies exactly at that point. It is not about learning technology, but about expanding your capacity for independent thinking. To achieve this, I want to start with the videos that received the most resonance. I will structure the creative intent as much as possible and explain the thought process behind them. I hope this time goes beyond simple production methods and leads to insights that expand your own way of thinking.

PCG is often misunderstood as merely a mathematical or programming technique, but in reality, the most important aspect is the planning-stage choices and design that determine "what kind of experience to create repeatedly." This course is an introductory lecture focused on understanding and utilizing PCG from a designer's perspective. Rather than teaching how to write code, it gradually explains why PCG is necessary, what problems it solves, and how it is used in game design, centered on principles and case studies.
