Game Rankings collects and links to (but does not host) reviews from other websites and magazines and averages specific ones. While hundreds of reviews may get listed, only the ones that Game Rankings deems notable are used for the average. Scores are culled from numerous American and European sources. The site uses a percentage grade for all reviews in order to be able to calculate an average, however, because not all sites use the same scoring system (some rate out of 5 or 10, while others use a letter grade), Game Rankings changes all other types of scores into percentages using a relatively straightforward conversion process. At this time Gamerankings is going through some system adjustments and have been for 12 months. Their interactivity options as message boards, sign-ins and user reviews have been disabled. No notification on when it will be enabled.
