What if someone implemented a class that inherits Game and serialized that
to an archive? When reading shared_ptr<Game> from such an archive,
serialization library does no know in advance which type should be used to
create an object, hence the need for a type to be polymorphic.

Adding a virtual function (e.g. destructor) fixes the problem for you?
