One thing I will say in regards to this whole choices / illusionism thing... is that I personally do not put nearly as much stock in having the ability to make meaningful choices as others do. Because quite frankly, meaningful choices to me are meaning
less if the results of those choices end up being bland, boring, incomprehensible, or just outright bad. If a poor-quality DM just doesn't have their crap together to produce fun and interesting content... the fact that I could
choose how to engage with it doesn't make it any better.
I will almost always take and play through a fantastic DM's personalized and virtually unchangeable, linear, railroady story over a DM who just doesn't do a good job, has bad stories and boring reactions but allows me to make whatever choices I want. There's a reason why 'Choose-Your-Own-Adventure' books are not seen as the highest level of literary quality, and it's
not because you get to choose the direction of the story.
