If you want to look at Witcher 3 sales, it paints the opposite picture you think it does. Witcher was a PC centric franchise with no history on PS and yet the PS4 version of it was the top selling version for the first year of it's life aka when it was full price.
You tell me what made CDPR more money, those full price $60 W3 purchases on PS4 where most of them happened or the discounted ones that came later on PC. This ain't rocket science, you can probably guess the correct answer... But anyways this is starting to get quite a bit off topic so just gonna revert back to not looking at your replies.
