I really do hate Nintendo doomsaying, but the Switch launch year had to be as explosive as it has been. The way I see it, without that hype, that mindshare, and the content to back it up, Nintendo would simply be back to "Okay" status. And if posting in videogame forums has ever taught me anything, it's that "Okay" is never okay.
That said, a few of these listed are enhanced ports from last generation. Not just simultaneous release, like with the PS360 stuff going into PS4/XBONE, but actual year + old ports.
I think the best launch prior to Switch that I witnessed first-hand was the Xbox, though. And that was accomplished with like, 1 game. Zelda and Mario are proving popular, I don't think anyone is surprised by that, but time will tell if the design of these games will have a lasting impact on games going forward in the same way that Halo did. Methinks Zelda will, but I'm unsure about Mario Odyssey. A few worlds in, and it's fantastic, but seemingly so unique it'd be hard to integrate the mechanics of it into other games.
EDIT: The Switch also has the surprise advantage of launching early into the year, feeding into the feeling of it having an amazing year, which, to be clear, it does, and I'm not trying to downplay it. But I know in 2014 when I picked up Sunset Overdrive it always felt like a "Year 2" kind of game, simply because of when it launched, even if that wasn't true.
