Topic: Claude Code x Games - Introducing solo entrepreneurship fields worth challenging using AI

The live session will mainly cover the following:
- Game industry trends (Unreal MMO related cases)
- Indie game strategies using AI and art generation
- Introduction to various directions and difficulty levels accessible through server utilization

Please refer to the details below.

=============================================

The second lecture in Rookiss's Pinpoint Lesson series is
[Server and Network Knowledge Naturally Learned Through Online Game Development].
The reason I chose this topic is...
First, I'll give you a spoiler with a game development project I've been testing recently.

Would you believe it if I told you all of this was created by AI?
In fact, all the game art was produced in just 30 minutes using refined prompt-based AI.
Although no one may have noticed yet, the era of the 1-person indie game developer,
who utilizes AI for everything from planning and art to programming, has truly x100 arrived.
If this level is possible now, aren't you even more excited for what's coming in 1 or 2 years?

It's becoming a very exciting time, as the art that used to trouble us so much is finally being solved.
But then, how should one go about making a game fun?
Of course, those with overflowing ideas can take on the challenge of a single-player game.
However, in terms of game success, single-player games can actually be more difficult than multiplayer games in some aspects.
While single-player games must have perfect balance and content creation to provide fun,
multiplayer games allow people to create content themselves,
meaning that if you nail the concept, the planning can actually be much easier.
Of course, the technical difficulty increases conversely, but even that is being significantly mitigated thanks to AI.

Ultimately, in a roundabout and unintended way, the value of the server becomes even higher.

Even if you don't necessarily have an interest in games,
the first place you'll hit a wall when developing using agents is the part related to 'servers and networks'.
What should you do if you want the app you worked so hard on to be used by your entire company or your friends?

Using deployment apps like Vercel with your eyes closed might work for the moment,
but as soon as the product becomes even slightly complex, that too is only a temporary fix.
Surprisingly, from this point on, a broad range of knowledge is required, including web servers, real-time servers, databases, cloud, and networks.

In [AI Core Essentials! Rookiss's Pinpoint Lesson], we have determined that the value of such server/network knowledge is
second only to Claude Code.
Therefore, we have selected [Server/Network Knowledge Naturally Learned Through Online Game Development] as our second topic.
From the concepts of Web Server / WebSocket / SSE / Real-time Server / Serialization,
to the ability to see the big picture through learning network knowledge,
we will wrap things up by seasoning it with a bit of security knowledge.
Ultimately, the goal is to create and operate a simple server with the help of AI.

Recording for this topic is scheduled to begin in the second week of May (once the Claude Code lectures are finalized).
While it will ultimately be released as an online course,
we will also run a challenge during the production process to provide live briefings and share directions on weekends.
We plan to provide the online course to challenge participants as well, giving it an "EARLY ACCESS" feel.

Recruitment for the challenge will begin this week, and a detailed announcement will follow.
A Live Seminar will likely be held over the weekend to provide further details.

(The following topic will be a Seamless MMORPG project for game developers.)
(And I am also considering an art production pipeline utilizing 100% AI as a future topic.)

Thank you!

Hello, this is Rookiss.

I have some news regarding the second-half-of-the-year series.

=================================

[First News] Introduction to Rookiss's Pinpoint Lesson

[Hitting the Core of AI! Rookiss's Pinpoint Lesson] Series Introduction
As the AI era approaches, unprecedented changes are underway.
Many people are struggling to move forward in this chaotic society,
but people often fail to realize that the way we learn has also changed significantly in the AI era.

The "10,000-Hour Rule" for becoming an expert has become a relic of the past.
Even if a person invests 10,000 hours, from an AI's perspective, they look like a cute beginner rather than an expert.
It has now become more advantageous for humans to know as many fields as possible as broadly as possible.
However, universities still conduct classes slowly using 1,000-page textbooks,
and academies still teach by having students type out code line by line.

That's why I prepared the [Rookiss's Pinpoint Lesson] series.
While covering a wide and diverse range of topics, the goal is to always move in a direction that is friendly to AI learning.
While striving to understand important parts persistently,
the overall volume is compressed to avoid unnecessary repetitive typing.

If you can accumulate more knowledge through one hour of content in a Pinpoint Lesson
more efficiently than 10 hours of self-study,
[Rookiss's Pinpoint Lesson] transcends from selling knowledge to selling time.

==================================================================

[Second News] Regarding the opening of a new course (KDC)

[KDC] Pinpointing the Core of AI! Rookiss's Pinpoint Lesson - Introduction to Claude Code

https://inf.run/Bemyc

The first lecture of the series is Claude Code, which is now an introductory topic for everyone.
- [1] Unlike other lectures, it does not focus solely on coding.
- [2] It focuses on the core nature of agents and Claude Code.
- [3] It is structured to make learning easy by utilizing self-produced teaching materials.

Since this lecture was planned with the goal of being part of the KDC government-funded program in the second half of the year, (assuming it passes the government evaluation successfully)
it is expected to be available for a self-payment of around 20,000 to 30,000 KRW by September or October.

=================================

[Third News] Regarding the next topic

And finally, the main news that marks today's highlight.

The second lecture in Rookiss's Pinpoint Lesson series is
[Server and Network Knowledge Naturally Learned Through Online Game Development].

The reason I chose this topic is...
First, I'll give you a spoiler with a game development project I've been testing recently.

Would you believe it if I told you all of this was created by AI?
In fact, the game art was all produced in just 30 minutes using refined prompt-based AI clicks.
No one may have noticed yet, but the era of the
solo indie game developer, utilizing AI for planning, art, and programming, has truly x100 arrived.

It is becoming a very exciting time, as the art that used to trouble us so much is finally being resolved.
But how do you go about making a game fun?
Of course, those with overflowing ideas can challenge themselves with single-player games.
However, in terms of game success, single-player games can actually be more difficult than multiplayer games in some aspects.
While single-player games must have perfect balance and content creation to provide fun,
multiplayer games allow people to create content on their own,
so if you get the concept right, the planning aspect can actually be much easier.
Conversely, the technical difficulty increases, but even that is being significantly mitigated thanks to AI.

Ultimately, in a roundabout and unintended way, the value of the server becomes even higher.

Of course, even if you have no interest in games,
the first part where you get stuck while developing using agents is the 'server and network' related section.
What should you do if you want the app you worked hard on to be used by your entire company or your friends?

It might work for now if you blindly use a deployment app like Vercel,
but as soon as the product becomes even slightly complex, this is merely a temporary fix.
Surprisingly, from this point on, a wide range of knowledge is required, including web servers, real-time servers, databases, cloud, and networks.

In [AI Core Essentials! Rookiss's Pinpoint Lesson], we have determined that the value of such server/network knowledge is
the next most important thing after Claude Code,
and have selected [Server/Network Knowledge Naturally Learned Through Online Game Development] as the second topic.
From the concepts of Web Server / WebSocket / SSE / Real-time Server / Serialization,
to the ability to see the big picture through learning network knowledge.
And we will wrap it up by adding a dash of security knowledge.
Ultimately, the goal is to create and operate a simple server with the help of AI.

Recording for this topic is scheduled to begin in the second week of May (once the Claude Code lectures are finalized),
and while it will ultimately be released as an online course,
we plan to run a challenge in parallel during the production process to provide live content briefings & direction sharing on weekends.
We intend to provide the online course to challenge participants as well, giving it an "Early Access" feel.

Recruitment for the challenge will begin this week, and I will provide a detailed announcement again.
A Live Seminar will likely be held over the weekend to explain the details.

(It's a secret, but the next topic will be a Seamless MMORPG project for game developers.)
(And I am also considering an art production pipeline utilizing 100% AI as a future topic.)
(Và tôi cũng đang cân nhắc chủ đề về quy trình sản xuất Art sử dụng 100% AI trong tương lai)

Thank you!

Hello, students.

As Anthropic officially discontinued the OAuth method for both business and individual users as of April 4th, our course has also been completely renewed from OAuth to the API Key method.

Not much has changed significantly, and the major changes are as follows.

• The permission handling part has been changed to the API Key method.

• Features related to plan usage do not exist in the API Key, so they have been deleted.

All 55 source codes for the entire course have been updated to the API Key standard, so you can download and use them as they are.

You don't need to worry just because it changed from OAuth to an API Key. The core of this course is building an agent from scratch, and that essence hasn't changed at all.

If you build it from scratch, you will be able to see the entire flow of the agent. In fact, many people have recently provided feedback saying they were "surprised that the structure and concepts are identical to Claude Code." As such, more than 90% of the concepts covered in this lecture are the same as Claude Code, and once you understand these concepts, you will be fully capable of developing agents using MCP or the Agent SDK.

Please do not be discouraged and continue to study hard as you have been doing. Thank you!

Hello, this is Rookiss.

Since several people requested a recording, I have opened the contents of yesterday's
[Rookiss Live Seminar] Survival Strategies in the AI Era - Physical AI and Future Job Responses
as a new free course.

https://inf.run/ZUxdk

Please refer to it as it covers important points I've felt about the current era.

Thank you!

Hello, this is Rookiss.

Due to the invasion of AI, many professions including programmers and accountants, which were once considered safe zones, are disappearing into history.
The current invasion of AI is already chaotic and shocking,
but from a macroscopic perspective, this is merely a scout.

This is because Physical AI, which will arrive in two years, can be seen as the main force of the AI invasion.
Once the invasion of Physical AI, represented by autonomous driving and robots, begins,
'most' of the tasks humans can do, including taxi/transportation/delivery/manufacturing/serving, can be replaced. What does this mean?

It doesn't just refer to 'some' professions like programmers, accountants, and lawyers.
It means that almost all jobs commonly held by people will be under direct invasion.
Even working a short-term part-time job at a convenience store or doing early-morning logistics work at Coupang
could become a luxury no longer permitted to humans.

Far from landing a job at a major corporation or buying a home in Seoul,
a situation may arise where you have to worry about your next meal today.
Looking back at human history, we will feel deeply that food, clothing, and shelter were never things to be taken for granted.
As the dissatisfaction of marginalized people erupts violently into chaos, further destabilizing society,
you might find yourself reminiscing about the past, grateful that you fully enjoyed the most peaceful era in human history, even if only for a short while.

When the era comes where humans command robots and robots do the work,
the meaning of a nation will fade significantly, and it would not be logically strange for an era to arrive where a small number of capitalists
manipulate humanity.
For example, wealthy Mexican cartels
could become more powerful than government forces by commanding robot armies.

No matter how brilliant a person is, they eventually die, and their knowledge is not perfectly transmitted.
However, the knowledge of AI is passed directly to other AI, meaning it can never regress.
Once you fall behind in the AI war, the gap will only widen, and a reversal will inevitably become increasingly difficult.
It is likely no coincidence that all big tech companies at this point are staking their lives on the AI war, even if it means manipulating their books.

The future I envision is also not bright.
However, rather than such a future arriving suddenly one day, there will certainly be a period of transition.
And this transition period might be the last opportunity to determine my future status.

Being swept away by the first wave of LLMs because you weren't prepared
is a flow of the times that truly no one could help.
But if you fail to prepare at all for the clearly predictable second wave of Physical AI,
then you must bear some level of responsibility yourself.

So, to survive in the future society amidst such chaos, what specifically should we prepare for?
I am holding a seminar to predict the changes coming in the future and organize what to prepare and study,
covering both short-term & long-term plans.

Hello, this is Rookiss.

https://inf.run/bD3b7

Today, after a long hiatus, [Unreal Agent from Scratch]—the result of Liu's research for a full 6 months—has been released as Early Access.
Please take a look at the amazing results you will complete in this course.

This course is not just a one-time follow-along using an MCP someone else made.
It is a course where you master fundamental technologies by implementing the Agent - Tool - MCP stages from scratch.
To summarize in one sentence, you can think of it as building an Agent like Claude Code from the ground up.

In the not-too-distant future, an era may come where games are developed with just a single "click" request.
Therefore, we have entered an era where we must continuously observe the advancement of AI,
and everyone must possess AI utilization skills as a basic literacy.

Although this course is themed around [Unreal Engine Agent],
knowledge of [Unreal Engine] is not required because it is not a course specifically specialized only for gaming.

Rather, since it is a course that demonstrates real-world examples of creating and utilizing Agents
using [Unreal Engine]—which is much more difficult than general Agents—as the subject,
if you understand this content overall, you will gain the ability to utilize
Agents in any field.

Please refer to the course introduction for more details.

Thank you.
