Famitsu claims that there are lots of different ways to fight, but doesn’t have many details on what that means. It introduces a blonde swordsman and a witch girl right under the bragging about battle variety, which is kind of funny when you think about it. “Play as the blue-haired swordsman or the blonde-haired swordsman! Did we mention there is a witch girl aaaand a healer girl?” These are the things that amuse me.
If you’d like to see a nostalgic look back at earlier games in the series, Square Enix posted a video for that here.
