I think it's overhyped, but it's not as if there's nothing good there.

It's goofy, it's got those building and travel mechanics people like from other games, you can capture a cute/funny team of animals that people love from pokemon, it's a good stream game with multiplayer which means lots of free publicity

I think it could be way better than it is, but it's easy to see how it got to where it is.
