Or you could consider the user of an interface, two classes that
implement that interface - and a factory class that returns the correct
one. You should pass some kind of object to the factory class, maybe in
the constructor; from which it can work out what type of class to
return. (Maybe the Game itself as a class/interface.)

This would allow you to add other types of class that implement the
interface for scenarios you have not yet imagined.
