Hi.

I want to create games but i don't know what engine to use.
I don't know a single line of code, so it needs to be easy.
And also being free helps a lot
for now i want to create 2d games
Sorry for the bad english

There is no “best” engine at all for beginners, you always have to get into it and learn the programming language of choice or else you'll be very limited in what you can do. Unity is C# and seems to be easiest to get into “scripting” which is a superset of C# language standard while Unreal is harder to wrap your mind to, especially because of their build system but you could use Blueprint to visually script certain logic.

Godot on the other hand is entirely free of any charge and has best 2D capabilities. I don't know much about their scripting model nor if they have something similar to Unreal's Blueprint

Thanks!
Later i found a good game engine
