I wouldn't really mind, as I generally don't care about reviews, but it would still be kind of strange. Why would you change them? Yuo review games when they come out, and usually, once they're out, people's opinion's on them changes. If you start changing scores, there'd be no end in sight. You'd have to constantly keep changing/updating scores, 'cos people's opinions and perceptions of quality would change over time.
