Say what you like about Square-Enix going downhill and not going back to their roots or whatever. They never went back to their roots because they always try new things, they innovate, they lead the way. I adore Final Fantasy as a series because of this. They're not afraid to do something different while many other games might prefer to just stick to what people liked last time and hope that they'll continue to like it forever and ever and ever (hi, FPS games).
