[Rookiss AI Creative GameDev - Live] Unity Indie & UE5 Tech Lab (January 2026 Class)

This is a level-up challenge for game developers preparing for the era of AI. In these times when finding a job has become difficult, what kind of future are you preparing for? Studying only game technology makes the future seem bleak, yet attempting only to release games makes growth feel unstable. If so, wouldn't the solution be to repeat the process of "releasing games while growing"? Starting from this challenge, we are no longer concerned about the average level of our students. This is because we have prepared all lectures across beginner, novice, intermediate, and advanced difficulty levels. In the Rookiss AI Creative GameDev Challenge, we have leveraged the characteristics of real-time live cohort education to prepare an educational system for everyone. If you can just bring your busy self to participate in the live sessions, you will feel yourself growing slowly but surely.

Introduction

I started game development out of pure curiosity to study hacking...
and as time passed, I have somehow become a 10th-year game developer.
"When will I ever finish making a game at this rate?"
Starting from basic syntax that makes you sigh,
to gradually building my own game world.
And the sense of pride when seeing many players connect to that world.
The more I study, the more I cannot escape the charm of MMORPGs.
I hope you can feel the same excitement that I felt.

A world in chaos 

An era where anyone can create products with the help of AI.
The gap between individuals and companies is narrowing,
and as companies are becoming extremely reluctant to hire,
employment may no longer be guaranteed in the future.


Shift in thinking

But if anyone can create products using AI,
is there really a reason to go to a company?
If you can earn enough money outside of a company,
your options will expand, and you will finally find freedom in life.

- University students worried about not being able to find a job.
- Job seekers in their 30s worried about employment due to their age.
- Office workers who are currently employed but worried about life after retirement.
- FIRE movement followers who want to achieve financial freedom through side projects.

Beyond that, anyone without exception should take an interest in the AI craze and start creating their own products.

*The curriculum is not 100% finalized and some content may change.

Unity Indie Lab & UE5 Tech Lab

Since AI only performs the tasks it is assigned, what you ask it to do is crucial.
And to direct its course wisely, it is essential for a human to have a thorough understanding of all concepts.
A defining characteristic of the AI era is that the productivity of a single exceptional senior has increased a hundredfold,
and this is precisely why entry-level hiring has stalled lately.

As a project grows in scale, the probability of AI making mistakes also increases.
Therefore, humans must now act not as workers, but as supervisors who give the final approval on AI outputs.
In the past, one could join a company as a junior and aim for steady growth,
but in this rapidly changing AI society, that ladder has now disappeared.
- [1] AI handles all the development.
- [2] Consequently, juniors cannot find jobs.
- [3] As a result, the motivation to learn decreases.
- [4] It is a natural trend that people are moving away from the basics and becoming 'fools.'

AI does everything, so juniors are not needed. Conversely, to utilize AI effectively,
a paradox arises where humans must reach an advanced level in the long run.
The long-term direction of Rookiss AI Creative GameDev is
to capture both the present (release) and the future (skill) simultaneously.
To achieve this, we will proceed with two curricula at the same time.そのために、2つのカリキュラムを同時に進行します。

Unity Indie Lab

This is an indie game development lecture conducted by Rookiss.
It combines theoretical study and practical exercises tailored to beginner, novice, and intermediate levels.
We will select a theme and challenge ourselves to release a Unity-based indie game,
while consistently studying various foundational knowledge required in the process to build up your skills.
The curriculum is conducted in one-month segments.

UE5 Tech Lab

This is a UE5 tech lecture conducted by Liu & Haker.
It is intended for programmers.
It covers advanced content, and a prior understanding of UE5 and C++ is essential.

In UE5 Tech Lab, we select one online game
and show you the entire process of creating it from start to finish.
We pursue challenging development by using the latest technologies possible rather than following conventional methods.
The sessions are led by Liu & conducted through reviews and discussions with Haker.
Since we proceed until a single game is completed, the curriculum typically continues in units of 2 to 3 months.

<Topic Selection>

The theme of Unity Indie Lab is Cat Management Simulation Game.

<A Message from Rookiss>

At one time, I really loved the various management simulations produced by <Kairosoft>. The graphics were simple, but the gameplay was excellent. I was also impressed by the company's business direction of churning out similar games by simply changing the theme. Of course, I also thought that if the graphics were just a bit cuter, they might have gained even more mainstream popularity.

On the other hand, there were games that I was drawn to immediately because the graphics were so cute. A representative case is <Office Cat> produced by TREEPLLA. Games featuring charming and fluffy cats have already established themselves as a popular mainstream genre and are loved worldwide without much preference (after all, cats are love!)

In this term, we plan to provide a sample game by transforming <GameDev Story> by Kairosoft, one of my favorite games, into a cat style. There is plenty to learn even in a seemingly simple game, such as the <Staff Management System> and <Movement through Pathfinding>. Let's build up our fundamentals through C#, data structures, and algorithms on weekdays, and immerse ourselves in cat game development on weekends to achieve both short-term and long-term growth.

Above all, if you can learn to use the assets produced directly by the Rookiss team with Nano Banana and extract your own art resources... wouldn't the direction for a solo game already be right in front of you?

The theme of UE5 Tech Lab is a Counter-Strike replica using the latest technology.

[Core Technologies Covered in This Project]
Iris: Concepts of next-generation networking, usage, and network optimization
CharacterMovementComponent: CMC concepts, network synchronization, and how to write custom code
UAF: Concepts and application of the next-generation animation framework (subject to change)
Gameplay Ability System: GAS concepts, usage, and network synchronization
Server Rollback Hit Detection: The most difficult technology in FPS, implementing fair bullet hit detection

<Message from Liu>

When Unreal Engine transitioned from 4 to 5, it brought revolutionary changes to rendering.
Nanite, Lumen - the graphics paradigm shifted.
So, what will change in the transition from 5 to 6?

This time, the core frameworks that directly affect the content level are being completely renewed.
The core logics we use every day, such as Iris and UAF, are being completely redesigned from the ground up.


In particular, the network system, which can be called the heart of Unreal, has evolved beyond the limitations of the existing structure
into a next-generation framework called Iris.
This technology has already been applied and proven in the field in Fortnite for two years.

It will be too late to learn these technologies after Unreal Engine 6 is officially released.
This is because many next-generation technologies have already been released at the beta level.
As an Unreal developer, you cannot stop evolving.


In this course, we won't just learn 'how to use' next-generation technologies.
We will understand the background and core concepts of why these advancements were made.
And it doesn't stop at just learning.
We will apply all these technologies in practice by developing CounterStrike ourselves.


I will organize and share many of the technologies I've researched this year,
and under the guidance of Haker, we will explore what top-tier domestic engineers think
about the future of Unreal technology.

    I mainly listened to the Tech Lab sessions, and the PPT you prepared was very well-organized with visual aids, which was extremely helpful. Additionally, it was impressive to have Heiker there providing advice alongside the presentation.
