Metacritic.com is a website that aggregates reviews of music albums, games, movies, TV shows and DVDs. For each product, a numerical score from each review is obtained and the total is averaged. An excerpt of each review is provided along with a hyperlink to the source. Three colour codes of Green, Yellow and Red summarize the critic's recommendation. This gives an idea of the general appeal of the product among reviewers and, to a lesser extent, the public.

The site is somewhat similar to Rotten Tomatoes, but the scoring results sometimes differ very drastically, due to Metacritic's method of scoring that converts each review into a percentage before taking a weighted average and listing different numbers of reviews.

Many review websites give a review grade out of five, out of ten, out of a hundred, or even an alphabetical score. Metacritic converts such a grade into a percentage. For reviews with no explicit scores (for example, Amazon.com's editorial reviews), Metacritic manually assesses the tone of the review before assigning a relevant grade. Weighting is also applied to reviews—those from major periodicals may have a greater effect on the average than niche ones, although Metacritic refuses to reveal what weights are applied to which publications.

Adam Donovan Sessler (born August 29, 1973) is a former co-host of X-Play with Morgan Webb and editor-in-chief of G4's game content for the network. He was the only remaining television personality from the G4's original incarnation until he and G4TV parted on April 25, 2012.

Sessler was born in Berkeley, California. He graduated from El Cerrito High School in 1991 and is a graduate of UCLA with a bachelor's degree in English literature. He was previously a credit analyst for a multinational Fortune 500 financial institution in San Francisco, and an actor on the San Francisco Public-access television show Chip Weigh Magnet Down, which he also helped to make. Adam admits that he is grateful to no longer work for Fortune 500 companies, saying in The X-Play Insider's Guide to Gaming that he was "very sad" about the job. Sessler currently lives in Los Angeles, California, having moved from the former TechTV headquarters, which was located in San Francisco, California. Sessler is married.

Some of Sessler's known favorite game series are: the Halo series for its first-person shooter qualities; the Japanese version of Rez for its Trance Vibrator feature; the Banjo-Kazooie, Rayman, Ratchet and Clank, and Sly Cooper series for their unique platform qualities; Resident Evil 4; and Call of Duty 4. He also stated during the broadcast of E3 2010 that Uncharted 2 was his favorite single player experience of all time.^{[citation needed]}
