Hello...am new here...which programming language should I learn that's best for game development?

Answer 1

Unreal Engine / C++:

https://www.UnrealEngine.com
Unity 3D / C#:
https://www.sololearn.com/Course/CSharp/
https://www.Unity3D.com
^Those are the two more widely used languages and engines in the gaming industry, so I'd recommend learning those first and foremost. They're very accommodating to the indie developer, and they're the most requested by potential employers in the industry, so it's overall good to learn them regardless of the route you wish to take with your career in game development (or hobby).
Now with that being said, they're not the ONLY options available but are certainly the better options from my experience with it. Many others have used Java and Python to create games as well and there are also engines available that support those languages.
If you're not in a rush or have a particular goal in mind, then I'd give all of the above and try to see what you personally enjoy best.

Answer 2

If you're just starting, learn C# and Unity
