An interesting review scale. But if you're making the scale non-standard already, why restrict yourself to a single axis? Why not have two or three? Fun, Truth, Beauty? Or one constant axis, but two others chosen for the game, to express whatever most needs expressing about it.
I liked the review itself, too. I feel I learned something, though I'm not sure about what.
Score:
Review Scale: 7/10
Narrative analysis: B+
Helpfulness for purchasing decision: Mediocre
