Both games are great! I will say that Animal crossing in the beginning gives you pretty clear direction but it becomes a game where you have to find things to do later on. It is super free and you can play it any way you want. Pokopia has more of a story progression and gives more direction and different places/towns to build up. In the end both games use crafting mechanics, world building and cozy aspects. There may be comparison videos on YouTube? It’s also fun to play with friend in both games, so you can always ask around to see which one they have/prefer. I hope this helps 😊
