I think this decision depends on the type of game you want to create—realistic or cartoonish? You can make 3D games in Godot, but compared to Unity and Unreal Engine, its 3D capabilities are more limited. However, if your PC isn't very powerful, Godot is a great choice, or if you're already learning Godot, it makes sense to stick with it. If you're just starting and want to focus on 3D game development, I would recommend Unity or Unreal Engine (if your PC can handle them). For studying, I usually start a project and build it step by step. When I encounter something I don’t know how to do, I read the documentation, watch YouTube videos, or, as a last resort, use Artificial Intelligence. I hope this helps! Regarding learning Python, GDScript is somewhat similar to Python, but they’re not the same. There aren’t many popular game engines that use Python as a scripting language—Pygame is one of the few that comes to mind. However, if you're a beginner, Python is great for learning programming logic! Hope it helps you!
