After Valve's new anti-review bombing measures kicked in, "off-topic" reviews were excluded from the review score by default. The change follows other platforms that have also had to take steps to address review bombing, such as Steam, which saw Borderlands 1 and 2 adversely affected after 2K announced Borderlands 3 will be a six-month timed exclusive on the Epic Games store. The delay is already in place, so if you're tempted to head on over to Metacritic to leave your views on Ghost of Tsushima or Paper Mario: The Origami King, which both released yesterday, a note asks you to "please spend some time playing the game" before inviting commenters to return a few days post-release. "This new waiting period for user reviews has been rolled out across Metacritic's Games section and was based on data-driven research and with the input of critics and industry experts." "We recently implemented the 36 hour waiting period for all user reviews in our games section to ensure our gamers have time to play these games before writing their reviews," a Metacritic spokesperson told its sister site, Gamespot. Metacritic reportedly confirmed the policy change wasn't implemented because of any one specific game but was instead "based on data-driven research and with the input of critics and industry experts". Review aggregate website Metacritic has implemented a 36-hour delay to its user-written video game reviews "to ensure gamers have time to play games before writing their reviews".
