GamesIndustry.biz has cited UK charts firm GfK, who claim that Red Dead Redemption 2's opening week physical sales in the UK are double that of its predecessor - Red Dead Redemption.
The game has "comfortably beat the first week's sales of Call of Duty: Black Ops 4." and "68% of the Red Dead Redemption 2's opening week sales came on PS4, with the remainder on Xbox One."
According to GamesIndustry, "Red Dead Redemption 2 is actually the third fastest-selling non-FIFA game released this generation - behind Call of Duty: Black Ops III and Call of Duty: Advanced Warfare. It sold slightly more physical units in its first week than last year's Call of Duty: WWII, and is well ahead of the fastest selling non-Call of Duty game - Fallout 4."
