Yah My post that was the idea at first, I just added the change in dialogue thing because it would make quests possible. It's not actually as hard as you think. I'm just having a hard time explaining it.
It is probably my lack of coding experience that would make me think it is difficult. I suppose to just use some kind of If;Then argument for a player to get a certain Item ID or reach a certain coordinate you could make things run smoothly.
