What example can you name in the industry currently that is a AAA single player focused title and isn't open world from a 3rd party that was successful.
So is that what you meant to say originally? Because large-scale single-player means large-scale single-player, not AAA single-player focused non-open world, which has a lot of caveats to it.
From just this year, Resident Evil 7 is the first that comes to my mind. The latest South Park game, and I'm about to start Persona 5 but have no idea whether it's open or not. Nioh was published by Sony but is now coming to PC that does will in both areas, similar to Bloodborne/Souls. The Crash 1 - 3 Remake sold like crazy and is as "traditional" as it gets to quote the other poster. Are we excluding platformers from single-player experiences? We probably shouldn't.
I realize many developers prefer open-world (Watch Dogs 2, FFXV), but I'm not sure why that matters? Just seems like developers like to make big worlds since technology supporters it now more than ever.
EDIT: I mean, from that last sentence, if that's the main point you're making, I don't disagree. I do disagree, however, that "traditional gaming" is dying since we'd then have to define it, but again, the post you responded to was in regards to another poster, not you.
