I totally forgot about Wii Party, oops! Just Dance was huge but it was third-party and I don't think it moved hardware much, more like Ubisoft striking gold by making a game fit for the userbase.
I still stand by what I said. Most of those games you list aren't what I would call notable, and that's just a matter of opinion. Wii sales were obviously going to go down regardless, I just think its decline could've been softer than it was. I just feel there was a lot of missed potential.
Anyways, I derailed this thread long enough. If Nintendo plays its cards right I could see Switch doing more of a Game Boy/DS hybrid sales trend.
