Smash 4 for it's horrid performance online. Splatoon 2 for how you're able to play with your friends. And I'm absolutely sure Pokemon Moon was for the horrid stuttering for the online battles.
Nintendo doesn't get a "pass" for this shyt. I think think the issue here is that some can find a little good in the bad, and it pisses people off for some reason when I'm sure it's the same case for literally every company.
Nether splatoon or smash 4 were knocked for having bad online, they always get excused from their online criticism with the "local play" excuse.
Pokemon moons online wasn't even brought up by reviewers.
If any other developer put out a fighting game or shooting game with online as bad as those 2 games, that game would be critically panned regardless oh how fun "local play" was.
