Metacritic

Metacritic is a website that aggregates reviews of media products: music albums, video games, films, TV shows, and formerly, books. For each product, the scores from each review are averaged (a weighted average). Metacritic was created by Jason Dietz, Marc Doyle, and Julie Doyle Roberts in 1999. The site provides an excerpt from each review and hyperlinks to its source. A color of green, yellow or red summarizes the critics' recommendations. It has been described as the video game industry's "premier" review aggregator.
