Good, they better get some of them sports games. They´re essential for their console to not be another WiiU.
Of course it´s not magically make it sell 80+ million units. But they need to start somewhere. It´s not about making the NX THE destination for sports games. It´s about having more and more diverse games on their system. More games period.
Not having Fifa IS a deal breaker for a lot of europeans. Most people only own one console per gen, so someone that might look for a nintendo console and sees then that it has fuck all 3rd party support, they´re not going to buy it. No matter how awesome it´s 1st party is.
"Everyone who wants 3rd party games, already has a PS4 or XboxOne" That´s just wrong. Like, just look at the numbers sold. Plenty enough customers to sell to left.
The whole ecosystem argument means very little honestly. People jumped from the 360 straight to the PS4 without even blinking. And i don´t buy the notion, that just because it´s mid-gen, Nintendo shouldn´t even try, not even try to get support, is just silly. Seriously, it´s not even about making the NX a major seller, it´s about starting to build an audience again, for the NX and then the future generations.
Just focusing on 1. party games is what the WiiU was, and will be the same thing what will happen to the NX, even if they can get more games by having their games work on both handheld and console. Minor improvement, but still a dead system. Their handheld would be fine, but you can bet your ass, that you´ll get wayyyyy less home console level games, if it fails like the WiiU did.
So even if you don´t care about sports games personally (i don´t), you better hope they can get EA to put Fifa, Madder, NHL etc. on there, cause if not, get ready for a repeat of the last 4 years.
