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.

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.

Due to personal coding standards, changing => does consume quite a bit of time. However, the quality of the code used in the lectures and the lecture content itself is quite excellent. I've already purchased the instructor's Skills module course as well, and I'm already looking forward to it.

The course broadened my development perspective. I liked the course so much that I immediately purchased the Quest & Achievement course as well! I would be grateful if you could upload many other courses in the future :)

This was so helpful! I feel like I've really learned how to structure quests, achievements, and more, and how to effectively utilize Events. I realized that I've been using Events in a very simplistic way until now 😊😊. I think I can apply this not only to quests but also to other systems. I need to review and get more familiar to build the structure myself, but it has been a great help in my recent work. Thank you! + Here's a suggestion for improvement! You do mention at the beginning of the lecture what you're going to create today, but sometimes it's hard to grasp exactly which UI it goes into and what the code is for, even while following along with the code. If you could show the goal of the lecture with visual aids at the beginning, it would be easier to understand and follow along.
