This is where Final Fantasy truly begins. Major focus on story, big ensemble cast, crazy music, wildly varied areas, cutting edge visuals (at the time), ATB, and more. The jump in quality between I-III and IV is absolutely mind-boggling, and playing them back-to-back only enhances it. Yes, the story goes off the rails by the end and the 20 fakeouts are pretty annoying, but man is it nice to see a franchise figure out what it truly wants to be moving forward.
