If there's one big moment where you could say they "sold out" it'd be FFII. Final Fantasy was to be their last game after all! They only made a second because the first got them monies. And boy am I glad they did. Those first few in the series weren't really my thing.

(Also, Crisis Core is pretty awesome if you both like FFVII and can ignore the existence of Genesis. He is by far my least favorite villain in the series, maybe even ever.)
