Think of all the money you will save though. If you are anything like myself you will never purchase a digital only game. how you will play them is when you get them for free or friends/family give them to you. I can honestly say that I will pirate digital only games before I will ever purchase them. (as bad as that may sound)
I'm with you. I really do despise digital-only games. I have them, but almost all of them are games I acquired through PS+ or some other method for free. Sure, I've bought some apps and a couple cheapies on the PS3 like Tori-Emaki and Aquatopia. But those were $1.99. I would never in a million years spend $20 for a digital-only game, let alone $60!
Everyone wants to speculate and drive some agenda into the ground that this is the last console generation, or that the next gen consoles will be digital-only, etc. I can honestly say I don't believe that and if some game company tries it, it's the end of my gaming with their systems/games. Sony experimented with it with the PSP Go. It was an abysmal failure and got dropped like a hot rock. Some say it was because it was "ahead of it's time" with it's digital-download approach, but I think it's more because people want to actually own something tangible. At the time of the Go's release, you could hit WiFi hotspots all over the place already so downloading the games wasn't the issue. And the PSP-3000 continued to sell well even after the Go was being phased out.
Digital game sales account for a very small percentage of overall game sales. I'm fine with developers and publishers offering games in both formats. Those that want digital, go for it. Those like us who want the physical game, we have that too.
I think when the next generation begins, it will start with Nintendo. They've filed the patents for a discless system, but that doesn't mean the NX won't have a drive. But with how out of touch and boneheaded Nintendo has been this past five years (I'm being generous, more like 20 going back to the bone-headed decision to make the N64 a cartridge-based system), I wouldn't put it past them to try it.
Microsoft tried a DRM scheme to lock individual games to one user and it blew up in their faces.
Sony seems to be the one company that will test the waters without jumping in head first. They try their hand at something and if it doesn't work, they drop it. The PSP Go? Wasn't popular so they stopped supporting it. PlayStation Move? Games weren't that big of a hit, stopped supporting it. Vita not a huge hit? Cut waaay back on support? PS4 focused on disc-based games first and foremost? WE HAVE A WINNER!
