I knew about it but hadn't realized how bad it is till playing it myself.What's the "it" you mean? I was referring to the fact that in the direct they showed off features like visiting other people's islands and doing island tours where you get to go to random non-player islands, meet new villagers and find new fauna and flora. Stuff like that.
The second person misses out on 90% of the game.
What do you mean by second person? I think the fact that multiple users on the same Switch have to share one island is definitely bad. At least should have been an option to have your own.
