    Comments about Godot Engine as an Alternative to Unity
    Comment summary: Godot Engine is praised for being free, open-source, and easy to use, making it more accessible, especially for beginners. It is appreciated for its lightweight nature, support for multiple platforms, and strong community involvement. Conversely, users point out it lacks advanced features in 3D compared to Unity and has issues with code editors for some languages. The upcoming development promises significant improvements, possibly narrowing the gap with Unity.

    It's more open, I can look under the hood ans see how things work. It's C# all the way down and performance is still great.
