Labo ain't doing shit, lol. Give it a rest. It is nothing close to Brain Training.
This is a new era, just enjoy, stop with the freaking cheerleading over an audience that's just fine and happy playing stupid games on their smartphones. If that's what they want, let them have it.
Nintendo has their own audience and it's not a small audience anymore they don't need some fat soccer mom who can't play video games to have to buy a Switch to be successful today.
Nintendo has always made games that families can enjoy together, that's not anything new or special. What's happening now is the successive build up of several generations of Nintendo fans growing into adults and quite frankly becoming a legion that can drive huge business. That's how you get your 12 million Smash copies in 1 month. It's no accident.
