This is a hard one to rank because its evolved so much. If I ranked it on my peek enjoyment (~Mirra release) it would be a 5/5, but eventually it grew to where I disliked it and I would rank it a 3/5

In my mind its a 4/5 as the story and some mechanics are lacking. But seeing as Im on my 5th playthrough my heart says its a big fat 5.
