Considering how big the Witcher is on the overwhelmingly digital platform that is PC it is no doubt much higher than 250k digital sales. It sure to absolutely dwarf the digital split for MGSV.
So let's recap shall we. First you say Witcher 3 is disappointing because it's sales aren't that much bigger than an established well known console franchise. Then you assert that CDPRs budget was higher than Kojima's (which honestly just lmfao at that. For real wtf were you thinking) Finally you say you would be so much more impressed if digital was 250k for Witcher 3 as if that wasn't a forgone conclusion. You sure are in a roll aren't ya?
I think Witcher is over 1 million on steamspy and all third party sites and retail PC copies activate on GOG. At least at launch CDPR said they had more GOG activated copies than steam.
PC is a pretty big chunk of W3 sales.
(this is all WW obviously), maybe there's some numbers in the region specific steamspy thread.
