Movies and Games are classified differently. Movies are classified by theme. Games are classified by core gameplay. As you said, it is subjective. Somebody might look for something in an RPG that others aren't. Subjectivity doesn't work in classification. Otherwise your classification system fails and you just have a whole bunch of views and opinions that people would have to adjust to in order to be on a common grounds. Also, scientific method works for everything. Every question you ask is solved with the scientific method.
Taxonomy works in a similar way.
http://en.wikipedia.org/wiki/Taxonomy
" Taxonomy is the practice and science of classification "
I think that is enough to prove that it is a very fitting method of classifying things.
