I think every game should be rated 2.718281...

Rounding is for the weak...

One of my favorite basketball cheers (we used it when playing against Rice):

The number for the review actually tells me whether I need to read the review or not.

For example, if a game I was already going to buy gets a 9 then I know I'll be getting the game. That way I don't end up reading about any potential spoilers etc.

On the otherhand, if it gets a 5 (ie LAIR) I'll read the review to see why it scored so low.

That still applies to a non number method with a smaller range.

If a game you are anticipating gets a "good" or "excellent" at the end of the review you will know not to bother reading the review (although to be honest I would read it anyway, because what if the review mentions something bad about the game that might not be a problem to the reviewer, but could be to me)
