Probably around 5 to 10% over all. But it is more like 50% digital on PC. I prefer to buy AAA games physically and indie games digitally since they don't take long to download. About 20% of my PS3 games are digital and 40% on Vita. I have alot of retro consoles, so overall the % is lower
Xbox One, PS4 and Switch (+ Many Retro Consoles)
