Review will contain mild spoilers: Please be wary.
This game is an RPG based entirely on dialogue choices. You can also move around the map outside of dialogue. This is how the game plays and some people may not find that fun. I, personally, did enjoy this system. I didn't want fancy mechanics, I wanted a story and this system was a brilliant way of doing that.
Through the duration of the game you will play a handful of different characters at different sections in the story. The story is broken up into several scenes and you will play one character until it is finished at which point both the scene and the character you play will change. And, unless the character is Asha (the princess of the human kingdom), you will never play as them again.
The way you end the scene, and the things you do during it, will effect future scenes in what characters appear (I have only noticed one instance of this but there are probably more) and characters will reffer to what your character did. For example you can run away from your marriage as a peasant girl in a farm village and the owner of the farm will mention that she has had trouble with a peasant running away in a later scene.
There are alot of examples of this that I could give which is wonderful. I love feeling that my choices mattered.
However I didn't get that feeling. I once tried to refuse to do something as one of the characters and the game pretty much said, "It is plot essential that you don't refuse so you did it anyway." In a game like this having control taken away from your character is pretty much the worse thing you could do.
The core selling point of this game is that the choices you do matter and if the moment you try to do something that will significantly alter the narrative of the story the game takes away your choices and forces you down a path then something has gone wrong.
The amount that your actions affected the world would be sufficient for a more combat-oriented game (in fact I would love it there) as the subtle strokes are so nice sometimes. But for this game it doesn't cut it.
But perhaps the worst feature of this game, the one that made me hate this game, was the lack of a suitable ending. In fact I thought I was still playing the game (the ending is done through dialogue between your character and another) and then it cut to credits. In this ending I learnt almost nothing about anything but the fact there is still tension between the humans and the naga; in every 'ending' that I got. (Even in my most naga-friendly playthrough it said, "The naga army may march on the humans." or something similar)
It was a neat idea about civil unrest and allowing you to play as characters who influence the story but I felt as though I had little impact on the narrative.
There was no closure on the stories of any of the characters (except for maybe Asha; but even then it is still weak) and I felt punished for being invested in them.
And the 'ending' was poorly executed and uninformative.
