This is an evolutionary project. It creates a basic RPG battle engine, then moves onto a more advanced engines. Compare FFI to FFX. The first engine will be similar to the early FF games. They will have the basic attack, item and magic options.
As the games advance, better graphics, physics, audio and AI will be incorporated. Also, summons, character swapping, character morphing, limit/super attacks, advanced strategy and more will be added. All this as the evolution continues.
