Unreal Engine
Epic Games' real-time 3D engine for games, film, VR and visualization.
Recommended as a ready-made engine that lets developers focus on the game instead of building tools123, and praised for high-end visuals and VR rendering.456 The most common complaint is that modern Unreal games run poorly or feel worse than custom-engine games789, followed by binary Blueprint files that text tools and AI agents struggle to work with.1011
Why people recommend it
Focus on game · 3
Commenters recommend using an existing engine like Unreal so effort goes into the game rather than the tech.
“If you just want to make a game, use a game engine like Unity, Godot or Unreal.”
“They focused on the game itself, and let the engine do the heavy lifting... to a superb result.”

“I stopped writing my own engines and used Unity, Unreal Engine, Phaser, Godot...”
Visual quality · 3
Its graphics and tech demos are described as better than in-house engines and other VR content.
“They focused on the game itself, and let the engine do the heavy lifting... to a superb result.”
“The best thing I seen in VR was the unreal engine VR demo.”

“There's improvement in tech - check out the Unreal Engine's tech demos for example”
VR and visualization · 2
Used beyond games, such as walking through a bathroom design in VR and character hair physics.
“I used Unreal Engine to set up all the materials, lighting, and VR stuff.”
“we then export into unreal where the hair responds to physics”
Python scripting · 2
Native Python and editor scripting work well, including for driving AI agents.
“Unreal use in Python is now native and users can launch a dedicated server.”
“In my projects i use unreal and me and my team have tested out multiple things.”
Industry skills · 1
Learning Unreal is recommended for getting work in the games industry.
“learn all the bells and whistles of Unreal Engine”
Caveats and dissent
Game performance · 3
Commenters say UE5 games often need frame generation, look blurry, or play worse than custom-engine games.
“If you look at the technical state of Unreal Engine 5, then how modern GPUs can barely run games without frame generation which also makes them look blurry”
“I don’t think unreal engine games play and look as well as custom engine games.”

“The average modern Unreal and Unity game feels like shit”
Binary Blueprints · 3
Blueprints are stored as binary, which makes them hard for LLMs and text tools to handle.
“That's a stark contrast to Unreal Engine's binary format for blueprints (visual scripting).”
“when I'm writing code for Unreal Engine in C++ & Blueprint I pretty much do it by hand”

“In my projects i use unreal and me and my team have tested out multiple things.”
Beginner complexity · 2
Its large feature set can make it hard for beginners to know where to start.
“Unity and Unreal Engine have too many features, which actually makes them less beginner-friendly”
“even with a really modular system like Unreal it gets convoluted”
Slow iteration · 1
Development can be slow because of compiling and cooking waits.
“Unreal use in Python is now native and users can launch a dedicated server.”
Quest development · 1
One commenter found developing for the Quest 3 with Unreal a poor experience.
“The best thing I seen in VR was the unreal engine VR demo.”
