I’m quite torn about Dorfromantik (a tile placement game) in this regard. The relaxing music and ambience, the beautiful graphics and the minimal interface and lack of time pressure all point to a relaxing game.

Getting a high score however – one of the game’s principal extrinsic goals – puts my brains into a bit of a stress modus because I’m mentally rotating pieces, moving around the board, evaluating probabilities and hedging against the luck of the draw. To play optimally actually takes a lot of focus.

You can build your landscape solely based on aesthetics but unfortunately most of the game’s unlockable content is gated behind milestones that can only be reached by a min-max playstyle. This is a conflict in the game’s design imo.

It’s worth mentioning however that the game also comes with a map editor in which you can place arbitrary tiles to create your dream landscape. You are completely free of any pressures but also can’t unlock additional content in this mode.

Minecraft is definitely cozy. I find assassin’s creed quite cozy too

The Guild. The ORIGINAL The Guild. It’s so atmospheric that, despite being all about running businesses and politics in 15th century Europe, it’s hard not to feel a sense of relaxation when you enter one of your buildings, the winter winds fading to a whisper behind you, as you look over your hard-working journeymen and the results of their labor.

Not joking, although I understand it seems very silly at face value.
Dark Souls 3 PvP specifically SL60+6 at gank town (after pontiff).
It used to be my go-to wind down after a work day.
It made me smile and actually relaxed me enough to go to bed and sleep, especially after a hard day.
