it has a weird, very japanese sense of humour, but very enjoyable. I don't enjoy making random miis, but the game has a "assisted" mii creastion tool that makes that less of a pain.
You can get very fun dialogues by inserting not-so-random prompts. And you can make things "happen" but also just watch while doing other stuff. I find it so far very enjoyable, and not very repetitive.
I've seen it being compared to The Sims, Animal Crossing or Pokopia. It's much more hands off than the first, and you do barely any interactivity in contrast to AC or Pokopia. Kinda like a movie you make an interaction every once in a while.
