According to Sakaguchi, an RPG is comprised of its world, its characters, and the events that happen in that world, which are told through cinematics. Unfortunately, the RPG genre is on the verge of being left behind by the rest of the world, he observes, which is why the definition of an RPG needs to change.
The question, then, is what to change and what not to change. Sakaguchi feels that what makes Japanese RPGs special are the smaller details and the emotions that bring the world to life. So long as creators keep these factors dear, hes optimistic that one day, Japanese RPGs will be accepted by the world.
