I'm still trying to figure out why folks here seem to think the numbers are bad. Maybe I am being dense right now and not grasping it. In several articles I have read...they state quite the opposite and most are impressed. I look at the last blockbuster game that sold like hotcakes for comparison. Not only did it sell well it also broke some records upon it's release; Spider-man. It seems pretty much on par with RDR2 upon its initial release.
Taken from a line in the article posted about the release weekend in regards to RDR2: "the company announced sell-through of $725 million during the game’s first three days of release."
From an article on Spider-Man's launch weekend (and can be found in numerous other articles includ Gamespot): USA Today says that this “opening weekend” would equate to around $198 million in sales, far higher than the $117 million box office opening of Spider-Man: Homecoming. This kind of thing has always been a bit apples and oranges, and I’m not sure whether it’s more or less impressive that games hit these marks with $60 sales instead of $15 movie tickets. Less sales overall, but at a higher price point.
