As mentioned earlier, Final Fantasy All The Bravest is strictly combat. Square Enix just released this launch trailer for the iOS game showing how insane that can get in parties this size. The trailer also gives you a look at how the old-school jobs, sprites and music are integrated into the game.
My advice: Use earbuds if you're playing this on public transportation. The game has launched in New Zealand because it's Thursday there already. It arrives in North America on the iTunes App Store tomorrow.
