different time though, in 2013 console games are mostly sold in physical (like 85%+), now it's below 10%~15% on PlayStation, under 10% on XBOX, and Nintendo still 40%~50% games sold in physical (if you include game-key card, the physical ratio will be higher, nintendo themself consider game key card as digital sale). also Sony alreay cut the blue-ray disc line only reserve some for game disc produce, manufactuering has cost (uncontrol consider complex market situation vs ditigal game)
PC in 2013 has 8% in physical, now full digital.
It's a industry trend, just like other entertainment, digital format become domiant.
