Re: Disk free
Steam showed the way on PC years ago, and in a very short time basically destroyed the boxed PC game industry, with any publishes not going via Steam, having to provide their own downloads, or create their own platform.
Big publishers like Ubisoft and EA have been trying to do the same to the console market for years, the PC versions of Origin and Uplay basically being practice for them.
The only reason I have any disks for my PS4 (first PlayStation I've owned) was that they were usually cheaper to buy than the online store versions (especially the legacy games, like early Uncharted games etc).
Personally, I don't miss having to use a CD/DVD to install stuff on PC.
