"Moving forward, Polygon editorial staff will have the ability to flag the reviews of certain games with a "Provisional" tag. If a review is marked as Provisional, then we're advising caution on the part of our audience. It means we haven't tested it enough in real-world conditions to be sure it will function as-advertised. Reviews marked this way will not be listed on Metacritic until the flag is removed. This flag should last only for a short window of time from a game's official release, until such time as we can make an informed judgment about its launch state."
