... and?
Final Fantasy has it's roots in Dragon Quest and D&D.
The first RPGs all took cues from D&D and every RPG since then owes there very existance to them.
Linear or Open-World, story heavy or story light, controlling the party or controlling there minds. None of this matters. What MATTERS is if the game is good, and 'Good Games' are not bound by Genre.
Seriously the Slime was inspired by a PC RPG named Wizardry. Shin Megami Tensai (the first one) was a BOOK adapted into a video game, hence the subtitle a Digital Devil Story, where's the report on that? Does any one care? of course not it isn't important, it doesn't stop SMT from being THE classic, it doesn't stop it from being the mother of all "God vs Devil vs Human" Psycho religious bullcrap to pop up in Anime, Videogames, Movies from all over the world.
