I was wrestling with the same question on my first Review D'Art, and I also would have preferred a half star at the time. But on the other hand do we really gain something that way? If we have half stars why not quarter stars as well? Is it 73 or 74%? It quickly gets silly. I think it makes sense to keep this very broad score and put the emphasis and the detail in the review and the pro-con list. Ultimately I think our reviews are anyway usually quite late and not necessarily used by many as the foundation of a buying decision. I think they serve as basis for discussion, as go to points for future reference, as "our point of view as a CRPG fansite", and I think the existing scoring format serves it pretty well.
