FF6 "Choose your own Adventure" style

My idea for a hack that I'm planning on creating is to allow players to make choices about where they are going to go next, what they are going to do in certain scenarios, etc, similar to Choose your own Adventure novels and/or gamebooks. The simplest ways in which players will be able to choose their route will be through dialogue options, but in some cases you will be able to choose a route through direct action.

This will obviously require a crudload of event editing, so it will be a long time before I have anything to show for it. I also want to plan out the major choices beforehand, so I won't even be editing for a while.

I'm planning on making instant death through your choices of route impossible or close to it. This is because the choices will not be based around survival, but accomplishing goals or making moral decisions instead. Some endings may be worse than others though...

This game will be based around the world of Final Fantasy VI. The backstory will essentially be that the character you are controlling is from the future, and got sent back in time (for reasons I'll figure out later). Before your character realizes what is going on, he'll accidently cause an issue in the main storyline (He'll cause Terra to be captured by the guards of Narshe early on), messing up the story a little. His main goal is pretty much a Back to the Future ripoff; fix the timeline and return to his time.

The character you are controlling is not supposed to be a faceless protagonist, or I'd have to make him really robotic or a heroic mime. He will start out fairly normal by our standards, and probably a little snarky. I'll try to give him some development as the story progresses, but I'm not a writer or anything, so I don't know how well I'll succeed. I am attempting to make it fairly serious; while there will be humor, it won't be memes or breaking the fourth wall.

The other characters will be featured as often as possible, along with probably a larger array of temporary characters. Gogo and Umaro won't be featured, as I probably won't be making a WoR segment (there's no structure there for choices to affect).

Gameplay will be a tough one for me. If you go through the same events after a different amount of time and chances to earn items/exp, you could have very different power levels. I may have to make different versions of the enemies to accommodate this in some places, and the game will probably have mild (in comparison to other hacks) difficulty so that you won't be stuck in any area. I may make parts more difficult based on your choices though.
