I haven't played much yet, but it's definitely quite different. I'm still getting used to the battle system, which is similar to FF15, but it feels a lot faster. I did find it kind of awkward to literally sit through 10-15 minutes of in-game cutscenes in the beginning after you already sat through 5-10 minutes of videos. 😛
In regard to the game itself, my only complaint so far is the lack of a sensitivity slider for the camera. In my opinion, the camera moves way too quickly as you move the right joystick around.
