I love classic FF (1-12), will I like this? I've been meaning to get it for ages, but I can never bring myself to do it due to the cost.
It's most comparable to FF XII in terms of combat and the scope of the areas, including overpowered foes strolling through the landscape to keep you on guard early on and come back later on. You don't have gambits to control partner AI, but you don't need an elaborate system when you can simply equip your party members with appropriate arts to make them behave like you want to. There's an occasional hiccup in AI behavior, but when you fail in combat, it's usually for at least one additional reason.
