Digital has been trending higher percentages steadily throughout the generation, but COVID-19 is what has accelerated the growth. I prefer physical, (though on Xbox One X the advantages in storage are negated by the massive 4k downloads) for storage, and collectible purposes. But since COVID-19 I have been buying digital save for once that I had to go to Walmart and saw a copy of Gears of War 4 with (the 360 games for free) included on sale for 15 dollars. Still the Xbox One X Download Even with the disc is like 118gb so...so much for that.
Just imagine what next gen will be like... and with ssd... very expensive to upgrade your storage...
