Why are strippers at the U.N. bad when they're great at strip clubs???
I'm not denying that it's always been good, but...I need to remind you that it's the Wii U we're talking about. The console was having mid-to-major problems in selling Nintendo games as well, up to the first half of 2014. Then, after Mario Kart 8 released, sales for Nintendo games got better across the board (aside from Bayonetta 2 ;_; even if it was the sequel of a title that went over 350,000 units in US with a major contribution from deep price cuts and it was having some sort of legs, up to January...). Mario Party 10 continues the trend.
Could be.
Personally I just think it's a continuation of the idea that Mario is synonymous with quality and people buy the title as a result of it, regardless of Wii U's trouble - best selling titles are with Mario as a headliner.
I think amiibo effect might be helping it too though to give credit where is due, in part with the marketing card you say so yeah maybe so but other first-party titles still sell like shit ;.;
