This has to be the best selling RPG of all time, right?
Skyrim is the only RPG I can think of that might have sold more than 30 Million. Maybe FF7R has a chance but that seems like a long shot.
Yes, Skyrim is still #1, it had already sold 30m by November 2016, which was 1 month after the XB1 and PS4 ports, and before the Switch and VR versions. Bethesda hasn’t announced updated numbers since then, but I would guess it has passed 35m by now, or at least close to it. Witcher 3 might catch it eventually, especially if they decide to port it to PS5 and Xbox Series, but I doubt they will, they seem to be fully focused on Cyberpunk currently.
