The Fairy Tree is a choose your own adventure story done in an audio drama format. Since there are multiple routes you can take, this review will follow the path outlined above. This playthrough erred on the side of being a kind, magical character and not fighting head on when you playing it smart can get you far. Call it my cautious personality.
The production value is top notch and worth the money you pay for it, assuming this style of story intrigues you. The adventure is short lived. At least for the path taken by me. Check out Zane's review for a different perspective and route taken through this fantasy adventure.
Headphones are key to experiencing the full effect of this audio drama. While it's not technically 3D as far as I can tell, it is highly immersive. That sense of being enveloped from both sides separates The Fairy Tree from free or even other paid productions. Again the price of admission is worth every penny.
It goes without saying that your mileage will vary. Not just because of the subjective nature of art, but due to the simple fact that your journey will be different from someone else's. Of course there's the caveat of limited combinations and permutations of plot events. Nowhere is this more clear, than when you're essentially given a redo for a decision you made early on in the story.
That's by far the biggest problem with this audio drama. It doesn't warrant repeat listens and there's no real sense of consequence for the actions you choose.
