PC market gives false readings. The reality is it is small for these type of games. It's highly distorted by the Asian market who will never play games like this, you can chase that 1 billion Gamers but the true audience is a few million at best.

That's why Steam is constantly dominated by f2p games and very specific genres, it's the Asian market floating those numbers. And also why a console platform with less than 100million users can outsell the PC market.
