Metacritic

Metacritic aggregates professional reviews into a single weighted score, and those scores have become a common reference point in the games and film industries.

Its influence extends past consumer decisions: publisher bonuses and studio decisions have been tied to Metacritic thresholds, which is a considerable amount of weight for a single aggregated number.

User scores are shown separately and behave very differently — they are open to coordinated review campaigns and often reflect controversy rather than quality.
