Sorry for the noob question but I've only just started C++ programming.

What I was wondering is what is the main language for programming commercial PC games?? I'm talking about the big ones such as DOOM or Quake, AoE and such. I'm interested in getting into the games industry later and I wan't to know whether they still use C++ or is C# taking over as the preferred language??

I realise that its going to be years before I can even think about building games like that but I was still curious as to where to begin.

Thanks in advance.
