Gonna have to disagree with you on that one. Aside from gameplay, the tone and story felt closer to a traditional FF game than, say, 13 or 15. A medieval story about multiple warring nations with crystals and an evil god wannabe lurking in the background. The game might be dark, but so were 2 and 4 which are the ones I'd put closest to 16 story-wise.
Hell, even for gameplay this is the direction FF has been moving in steadily for the past several games. From 12 to 15 there was a fairly straightforward march from traditional turn based to steadily more action-oriented. This is the natural next step in that chain.
