Final Fantasy 12 battle system

Good point, so far the idea is the FF12 combat mechanic maybe mix it with the Clive Barker’s Jericho character swap mechanic if the main character is down and has a party, if just alone then character will die and build with a Kenshi style sandbox or if I did a horror style game then go with an Fear & Hunger style smaller world. That would possible be a hub world or semi open world.
