I did call Godot lighter than Unity or Unreal, which I believe to be factually accurate. I have run Godot on a 2014 era laptop, it runs well on a system of that vintage.
It is a full featured 2D/3D game engine and development environment, which can be a lot to take in. A lot of what I learned about game development I learned from a Youtube channel called Clear Code, who made the same snake game in both Pygame and Godot.
Python and Pygame does away with the cluttered IDE, and you can build a functioning game in one file, then you translate those concepts to a more full-on game engine which is going to be a bit more practicable for making larger games with things like tilesets and more complicated physics and collisions and whatnot. I'd hate to try making a Zelda-like game in something like Pygame. Fear the men who made A Link to the Past in 6502 assembly.
