Last year they tried to prevent piracy, but somehow, similar to the style they get their job done, they failed and it just took longer to crack the game. I remember that for PES 2016 you could also play online with some sort of cracked files.
I honestly really hoped last year for the game to not be cracked so in this way they will have higher incomes and those will be invested in the PC version, but everything went havoc in November. Getting the game cracked really pissed them off, I think this is the main reason why we didn't get Anfield or SIP on PC ...
So are they really take the PC version forward or this will be their better version of PES in the following years as they will lose their partnership with Sony ?
