Metacritic interview on IndustryGamers chats with Marc Doyle, games editor at Metacritic, who talks about the impact of metascores on game sales. They also discuss some of the mechanics of the system, including the reasons for weighting scores from some sources over others. As for article's main premise, Marc says there's no scientific way to correlate the impact of reviews on sales, though he does agree there often appears to be a relationship: "Anecdotally, however, it does appear that many of the best selling games often have very high Metascores (Red Dead Redemption, Halo 3, Half-Life 2, Grand Theft Auto IV, etc.) There are, of course, exceptions on both ends. Enter The Matrix sold very well with a middling Metascore, and Beyond Good & Evil didn't find its audience despite a very strong Metascore. Again, the influences of strong licenses or lack of marketing/awareness can often help a mediocre game or stifle a very good game."
