Recently, after experiencing the red Unity license incident.. I started studying Unreal Engine, which I had been putting off for a long time.

It's been a long time since I last installed Unreal Engine 5...
Even on Mac, it feels like I'm installing it for the first time, though I had heard it works well on Mac now... It's working very smoothly.
Actually, I haven't used Unreal for the first time; I bought and tried it back when Unreal first started supporting mobile. (I paid for it but didn't use it.. I don't think I got a refund.. )
Since I bought and tried out Unreal 4 back in 2014 when it started supporting mobile, I remember getting a head start on it compared to others in Korea at the time.

However, at the time, I was only working on 2D-focused projects, and although I occasionally did 3D projects, I had made up my mind not to do high-quality 3D work due to past PTSD... (During my time in the lab... I met monsters too early..) It didn't seem like my path, so I stopped studying and researching any further.
And at the time, it was incomparable to Unity in terms of speed and was rough, and the Blueprint development style that Unreal pushed was not right for my development definition, so I decided to ignore it.
And after almost 10 years have passed.. Now it's not Unreal 4, but Unreal 5, so I'm in the process of installing it.. It feels like it's somewhat similar, but it's changed a lot..

Actually, one of my main areas of work is not just simple game development, but also immersive content fields like VR, AR, and MR. In those fields, there are many technologies that garner attention in the Unreal Engine realm rather than Unity, such as the recently emerged Meta Humans or technologies that create virtual content by combining real-time technology. That is why many people around me have been asking me why I don't use Unreal for quite some time.
Well, I guess... every time, Unreal just felt too heavy.
While I answered that, if I were to describe my current feelings, I feel like I'm cheating on Unity by touching Unreal... no, I feel like I'm abandoning my heart. It felt like a huge sense of betrayal.
I guess I'm secretly a romantic.
Anyway, seeing the woman (?) I trusted so much betray that trust by making ridiculous claims (changing the subscription plan), even if she apologized and talked about other things, the broken trust wouldn't be easily restored...
I think I'm also going to look for a new person (engine).
Sigh...
It's true, the expression is a bit much...
It feels like the emotion of having to let go of a very old lover who cheated on you.
No, rather than that, is it like the heart of a fan who was greatly disappointed to see a different side of me than the one they had supported for a long time?
Starting My Journey with Unreal Engine 5

Now I need to meet many new people (the engine).
I should try a high-end engine and try other engines too..
Just as I happen to be lecturing students at school these days, I thought that what they can do with Unreal Engine would be more helpful when they graduate and consider employment or starting a business, so I decided to study Unreal Engine first.
