I started with New Leaf, and I like this better already. I also am puzzled by people who are out of things to do, there's still so much for me to do. I also don't trade much so maybe it's that. I'm still looking for new things to catalog and looking for DIYs and bugs and fish for my museum (not to mention art) and I just decided to redesign my residential area so that's going to be a ton of work over the next three weeks. I don't have dreamies so I am eager to see villagers move out and get new ones, whether via someone's void or a Nook Miles island or a random move in or a campsite visitor. I like the dopamine hit of completing Nooks Miles tasks (though I don't complete ones I think are annoying). The game doesn't feel bare bones to me, but I think I had different expectations going in than most people on TBT (honestly I had almost zero as I watched only the announcement trailer and engaged in zero speculation). It's not perfect, there are things that annoy me, but overall I'm really happy with the game.
I see so much negativity about the game here, just wanted to share a positive perspective.
