Zrevnur: Strange that HOMM3 is #1 though - never understood that... TBS arent that popular...
toxicTom: Maybe... but HoMM3 is like the perfect game of its genre.
I think Witcher 3 would be No. 1 if they merged the base game and the GOTY-edition.
That's a good point.
According to the sites pasted below, Witcher 3 sold over 28 million copies, over 12M of which were on PC.

Can't find any current numbers on Witcher 3 sales between GOG vs Steam, however, it sold more copies on GOG than on Steam at launch, reportedly.
Even with this info, it's difficult to guess the number of copies Witcher 3 sold on GOG, therefore even more difficult to assume anything about CP2077 or HOMM3.
Maybe it'll be easier to gauge how much HOMM3 has sold when CP2077 numbers are reported.
