As a fellow game developer, I have to agree. I find that inheritance is a form of abstraction which sounds nice on paper and may work well within some domains, but in large and diverse code bases (like in games), it makes code harder to reason about and harder to safely modify (e.g. changing a base class can have a lot of subtle effects on subclasses that are hard to detect). The same goes for operator overloading, implicit constructors... Basically almost anything implicit that is done by the compiler for you and isn't immediately obvious from reading the code.
