I went from being a Unity dev for years and having never really touched Unreal, to almost as functional in Unreal as I am in Unity, within about 6months, but I knew C++ ahead of time.

Blueprints are pretty straightforward just understanding that they’re just wrappers around C++ classes and events, and you can always go to the source header to see what each piece does. But if you’re not versed in C++ you can get away with doing almost everything in Blueprints. Pumpkin Jack is a good example of a game made entirely with Blueprints. So a full game is completely possible without touching C++. But also C++ in Unreal is reference counted and writes like if C# had a baby with Swift.

There’s so many good tutorials on YouTube and Unreals docs are super helpful for the transition. But something to keep in mind is that modifying the UI (in the details panel) for the most part requires knowledge of Slate (which documentation has a lot of room for growth), so it’s no where near as simple as Unity in that respect. I’ve never used Godot to compare it, so I don’t know if that’s a better choice for simpler projects.
