We've always debated (and still are) on what would it be like to have Saber as your personal servant? Well, she technically is, as you are bound to her by master/servant contract on the first night you met in any game of Fate. Except you are stuck to the arcade type versions like Fate/Unlimited Codes, which kills the feeling of "owning" her, ya know?
From the screen shots, it definitely looks like a Persona 4 to me, along with the battle concept. And that's a good thing people... (go play P4 to find out how good!)
So incorporating this idea ain't too bad. A free dynamic environment with power-ups (hopefully) like in FF series?... kinda nice. Having it simulate FF is wishful thinking as I can only pray the graphics are upped a lot more.
