I still don't really understand even after watching it. I'm not absorbing anything at all. It is difficult to understand the skill system just by listening to this lecture because there isn't enough explanation. I believe it is necessary to provide thorough, step-by-step explanations tailored to the learner's level and to use diagrams where necessary to aid understanding. I think the teaching method needs some improvement. This style of lecturing does not seem to be effective for learning.

I think the modular approach is a good method. It's difficult to understand the lecture content just by looking at the code and listening to the explanation. I wish the explanations had been easier to understand.

I couldn't find a satisfactory method for creating and managing complex skills even after browsing through countless YouTube videos, blogs, communities, and paid courses, but here it is

Since I'm a C# beginner, it was really difficult at first. It took me 3 hours just to watch one lecture. Concepts like delegates and events were unfamiliar, and I didn't even know Unity had custom editors. Now I've gone through it more than 3 times, applying it to personal projects and creating additional quest and achievement systems beyond just the item system. Through this practical application, I'm starting to understand it better. This is such a great lecture that can be applied to various projects. Personally, if you have any game development projects, I'd love to see your game development process too.
