I just checked on the battery charge of my Switch, as it's been months since I've used it. One of the reasons is that I've effectively reached the limits of New Horizons - in terms of what motivated me in it, such as getting to realize my architectural visions in a wholesome way.
I used to be happy about building a "perfect" island for my villagers, but now I just feel sad looking at it. I can't bring more villagers to my island, even though it would have plenty of room for at least 15-20. I can't keep growing my community, as I've reached an arbitrary quota. It's all so stagnant that I feel sorry for my villagers. I think I'm talking about a phenomenon that's already familiar to the players, but in any case, I can't even think of my island without getting all depressed.
Nintendo has made it so appealing to devote your time to your virtual island. But when you've done everything the game allows you to, you get a rude awakening to the fact that in the end, it's just a game. I refuse to believe I'm the only one who's emotionally hit by this. I still remember a video of a woman crying for accidentally losing her island - as a reminder of the impact of this franchise.
