I see many people saying "unity" and stuff... People... Unity and others are GAME ENGINES not programming languages....
I could recommend to start with C# as it is a pretty good language for game dev and is easy to learn, once you get used to it enough, you could start C++ and C, once you know C# it is very easy to start other languages.
You can learn C# for free directly from Microsoft here https://docs.microsoft.com/en-us/dotnet/csharp/tutorials/
I think it also depends about how the assets are packaged with the game, multiple CC licences technically prevent making the assets impossible to obtain, the packaging process of the game engines where it puts assets in a proprietary file format might violate this rule, however, loading the assets at runtime from a directory where they're in an easy to read format doesn't violate it
