any game can be made with C++. its probably the only language that can claim that (other than assembly perhaps). other languages tend to have issues that make them unsuitable for particular types of games.

I think most languages are capable of creating most games. To create them with a good level of polish however and high definition graphics etc. requires more than your language itself as you need a way to write shaders and talk to the graphics card (which is hlsl or glsl) amongst a whole host of other language neutral stuff...
