Multimedia adaptation for The Witcher has skyrocketed the franchise into unbelievable heights.

Wouldn't this make The Witcher 3 one of the best selling, if not the best selling, RPG of all time? At the very least it should be past Skyrim.

Maybe. Maybe not.

Skyrim sold 30 million copies back in 2016, announced one month after the release of the PS4 and X1 version. So you have 30m plus LTD sales of the PS4 and X1 version (minus the first month), the Switch version, the next gen version and of course the PC version since December 2016.

Could definitely be over 40m.

Diablo 3 hit 30 million in August 2015, only three years after release.
Wouldn't be surprised either if that one is over 40m.

Hard to say:

Touching on the success of The Elder Scrolls V: Skyrim, Howard noted that it's "far above" 30 million copies sold, though he didn't provide a new number. Skyrim Anniversary Edition is scheduled to launch on Nov. 11, 2021, with a free current-generation upgrade for anyone that owns Skyrim Special Edition.

So, Cyberpunk had 13m at the end of December 2020, it's release month. From 13m in the first month to 5m across the next 16 months, ouch. The poor launch really killed their legs, the game has been in sales for as little as $5 and they still only sold 5m since that first month. It's actually admirable that they are still working on fixing it and still doing the expansions for it, a lesser developer/publisher would have already cancelled ongoing development to move the Cyberpunk team to their next project, Witcher 4. 

Witcher 3 meanwhile was at 30m April 2021, so it sold 10m in a year, very good sales for a game from 2015. Witcher franchise was at 50m April 2021, meaning the franchise has sold 15m in the last year, 10m of which was Witcher 3, and the other 5m split between Witcher 1, Witcher 2, and Thronebreaker: The Witcher Tales.

WHen AAA devs fuck up a project but people give them a free pass anyway. "but they updated it" shouldn't have been a mess in the first place.
