Unreal excels at high-fidelity rendering and real-time production; for lightweight mobile or a quick start, a simpler engine may fit.
About
In practice. What you can do with Unreal Engine.
Unreal Engine is Epic Games' real-time engine, and it's probably the most powerful 3D software you can use for free. Born for games, it's now everywhere: architectural visualization, film virtual production (LED walls like The Mandalorian), motion design, car configurators, simulation. With Lumen (real-time global illumination) and Nanite (massive geometry), it produces real-time photorealism, changing how people work.
The business model is very generous: Unreal is free for creators, with only a 5% royalty on games that exceed $1 million in revenue. For some non-game enterprise uses, a per-seat subscription exists. For the vast majority of freelancers, it's free.
The downside is the learning curve: Unreal is vast and technical. For simple, fast archviz, Twinmotion (built on Unreal) is far more approachable, and Lumion or D5 Render aim for the same ease. But the moment you want advanced real time, interactivity or virtual production, Unreal is the reference, and its unbeatable price (free) makes it a must-know.

Pros and cons. What Unreal Engine does well, and what to expect.
Pros
Benchmark real-time rendering quality.
Free while revenue stays below the threshold.
Blueprints for no-code prototyping.
Strong in film and virtual production.
Cons
Demanding on machine power.
Steep learning curve.
Royalties above the threshold for games.
When it makes sense. Keep Unreal Engine, or challenge it?
Keep if
You target high-end graphics.
You do AAA games, virtual production or archviz.
Challenge if
You mainly target lightweight 2D mobile.
You have limited machine power for the editor.
Our verdict. What to know about Unreal Engine.
Why this verdict
Great
Unreal Engine is fairly easy to replace with an alternative, a free tier to test before paying, clearly documented use cases.
