Game engines absolutely not. They're almost all written in C++ with exceptions and RTTI disabled and no STL. Gamdev C++ can better be thought of as C+. It's kinda sorta not the same language.

However, a lot of game engines use GC languages to operate game logic. Lots of them use Lua, unity uses c#. The ubiquity of Lua in gamedev has resulted in luajit being shockingly good if you're pushing around a bunch of floats.
