I’d say in my ignorance, that would not be ideal, and there should be ways to control that to the desired level via hard programmed limits. An example would be CP2077, there is a main story with variables, the game is designed to present this story. The way I see it, the variables would arise in a more orangic fashion, and would also allow for correction of self induced errors, such as a decision you make and later change your mind.
I don’t like that the Phantom Liberty DLC being plunked down near the end of the main story, because it’s messes with the main story. This is why you’ll read comments like play the game though to the end first, and then go back and pick up that story, which feels artificial to me. AI might possibly make insertion of a DLC into an existing story easier and more fluid. No Telling how many jobs it might cost… 🤔
