Just take a look at how many RPGs are having the word "action" in their desctription nowadays. None, if I see this correctly. Nowadays, ALL RPGs MUST have this attribute, or … well, at least marketing from all around the world believes it won't never ever sell.

That's a very subtle kind of domination, imho.
