You almost always want to use C++ for serious game development for performance and so you can easily use C++ game dev libraries and toolchains. You can use C, but you will almost certainly have to use C++ libraries anyway, so might as well suck it up and get used to C++. Most people use a strict subset of C++ because there are definitely C++ features that lead to icky code.
If you want to make some 2D indie game or a slow ass bloated 3D game like minecraft, go ahead and use another language. It's certainly possible if you don't need the performance or fine tuned control over memory usage. I'll still be waiting over here with the pragmatic programmers waiting to shake my head and tell you I told you so when you run into all kinds of bs that you have to workaround that wouldn't be an issue if you used C++.
