Unity is easy to use once you've figured out how it all works. They have great tutorials to help you learn how to use Unity

Unity is good if you're C# fluent. But Unreal has Blueprint which transform coding into visual scripting:

My take if you're starting game coding, ask an AI chatbot like ChatGPT for complex classes or even as the baseline of your game architecture. These days. I use both Grok and ChatGPT, they are very helpful.

try godot or gamemaker

Unity, Unreal and Godot are all some good ideas. Overall, I'd recommend trying them all and see which ones you are best at.
