Metacritic only accepts the first review and first score published for a given game by a given publication. We are explicit about this policy with every new publication we agree to track. It's a critic-protection measure, instituted in 2003 after we found that many publications had been pressured to raise review scores (or de-publish reviews) to satisfy outside influences. Our policy has acted as a disincentive for these outside forces to apply that type of inappropriate pressure.
