While a hit with Hardcore gamers, the Switch is also a great system for more casual players as well thanks to its simplicity and pick-up-and-play nature. Several of Nintendo's titles like Nintendo Labo, 1-2 Switch, and Mario Kart 8 DX are all geared towards more casual audiences. But, they also all follow the family friendly aesthetic Nintendo is known for. For that reason, do you feel Nintendo should try it's hand at "mature" casual games. As in, games that are simple and aimed at those who don't play many games, but with themes and content that aren't so child friendly.
Not necessarily blood and gore, or M rated. But something geared primarily towards the early 20-something casuals Nintendo has primarily marketed the Switch to so far. Stuff like Hotel Dusk or Night in the Woods is where I'm getting at.
