I've never noticed this at all. Do you have any actual production numbers for physical games besides just what you personally collected for your own collection? Have you looked into regional differences between physical releases? Did some countries get more than others for different generations? There's still a lot of unknowns here.

Even if there's less physical releases for PS3 for different games, it felt like each game had at least 3-5 different versions to purchase. I would avoid buying a physical copy if just a year later a newer version came out with all the added DLC and extra features.

As of 7 years ago, someone claimed to own 1194 retail released North American Xbox 360 games. That's still more games than the NES had released.

Personally for myself for the Xbox 360 and PS3, I own less than 10 games for each console. There's just so few games I feel are worth owning for either of those consoles. Maybe I'll add more if I come across certain titles in the future, but still not too many.
