Metacritic restricts launch day game reviews to limit trolls - SlashGear
Metacritic is the latest website to take steps to prevent review bombing,' the practice of plastering a game, movie, or TV show with negative reviews as soon as it is released. These attacks are often politically motivated and intended to harm the production in an effort to prevent the creation of similar future works. In Metacritic's case, it is restricting early game reviews.
