Just in case breaking the 70 million shipped copies milestone and grabbing two Steam Awards wasn't enough, GTA 5 is still making headlines with its immense success in spite of being over three years old. To top off the Steam holiday sale, Valve has revealed which games sold the most copies via their digital distribution and slapped a discount on them all.
There exists a prevailing misconception among GTA 5 fans that the PC demographic is tiny compared to console players. This is in spite of an overwhelming amount of evidence to the contrary, including the extremely active and vibrant modding community, as well as the special attention Rockstar turned to solving the hacker issue on the platform.
While Valve didn't reveal exact numbers (they're probably not allowed to) they did group the various games into tiers of how well they performed from a commercial standpoint, with "Platinum" games being the top dogs, and GTA 5 is among them.
