@k8 I tend to collect (hoard) more than I get a chance to play, so this list is much shorter than it should be. 😂

A Short Hike. I put off playing this for way too long. It’s so good.

Lost Nova. I never see this one mentioned! The writing is great (very relatable dialogue) and the vibe is wholesome and the colour palette is just beautiful.

Spiritfarer. Parts of this are decidedly not cosy, but overall it’s a really cathartic and meaningful experience. There’s no other game quite like it.

Cozy Grove has been mentioned. Its developers, Spry Fox, have also made Cozy Grove 2. The second game was Netflix- and mobile-only, but since they’ve regained their independence it’ll be coming to Steam. They’re also working on Spirit Crossing, a cosy mmo game. I played an early build (it’s still in alpha) and loved it.

Speaking of cosy mmo games, I second the Palia recommendation, and I’m keeping an eye on Loftia, which is currently in beta I think.
