I'm not a hardcore gamer, but usually mostly into RPGs. But I've also got hundreds of hours in stardew and thousands in the Sims. When I play one of those, I'm always low key scared to grow bored because I LOVE those games and I know that there won't be another good one right around the corner.

When I got bored of Skyrim, I played the Witcher, and when I got bored of that, I played Fallout. Repeat ad nauseam, because there's more playable, entertaining RPGs out there than any one human could play in a lifetime.

With cosy games, not so much. When you grow bored of one, chances are, there won't be another one that'll be enjoyable to you at all, and you'll have to hope and wait that something good will come out at some point.
