That's impressive, no matter how you look at it. For context, while the last entry in the franchise did sell well over 8 million, including selling eight million on the Nintendo Switch alone, it wasn't this quick! Or even get close to this quickly. What does this prove about the game? First, it proves that the franchise has truly grown and expanded its player base with the last two mainline entries, both of which helped break some of the "new player barriers" that limited how successful games were in the past. Second, it shows that Capcom really did well in expanding the game's abilities and styles, as there were plenty of new things within the game to make it stand out more. Finally, Capcom marketed it well and ensured gamers were hyped for it. To be fair, there are some flaws within the game, including on the Steam version, where Capcom is racing to fix some performance issues. Even still, this is a milestone moment for Capcom, and that should be celebrated.
