Any summary review of a game or movie or book that is based on an "out-of-5-stars" or "X-out-of-10" system is always going to be slightly misleading, because it represents a very, very broad reaction by the individual doing the review to the game. With this system, we never really know the thought process behind the score--particularly what the reviewer did and did not take into account when summing up his thoughts.

For it to be a little more accurate, I think we'd need some kind of justification system, like:

SCORE: 10/10 BECAUSE OF: original story, strong characters, voice acting IN SPITE OF: buggy cutscenes, unoriginal gameplay, weird ending
