The purpose of the site Metacritic is well-known to many folks. Just in case you don't know, it is a site that takes the reviews from various critical sources for various media (games, movies, etc) and posts a numerical average of all of the scores. This, in turn, is used by lots of people who can see the overall gist of how quality their product is, based on a 1-100 scale.
Unfortunately, when it comes to video games, you find most often that the scale shrinks (this, of course, being the fault of critics), to a 7-10 scale. Only the truly atrocious/unplayable receive below that mark, and critics of late have been much more generous in dishing out the perfect 10s (which is idiotic). If a video game gets an 80 or lower on Metacritic, it is practically doomed to fail.
