Thank you for the wonderful list. Here are some other suggestions that I haven't seen mentioned yet. Apologies for not describing or linking to the games:
- Reventure (highly recommended)
- Recursed (same)
- Treasure Adventure Game, or its remake Treasure Adventure World
- Loot Hound (so relaxing)
- Wilmot's Warehouse (same)
- Out of Space (the opposite of relaxing)
- Q.U.B.E.
- There Is No Game
- An Untitled Story
- Tools Up!
- Viscera Cleanup Detail
And of course the well-known (as far as I can tell) Terraria, Minecraft, Stardew Valley, Undertale, Stanley Parable, Dicey Dungeons, Keep Talking And Nobody Explodes, Firewatch, Transistor, Overcooked.
Note that a few you recommended are already in the list or in other sub-lists, you might have missed them if you only reviewed the "for non-gamers" sub-list that I linked to. For the full smorgasbord, check out https://ronan.jouchet.fr/games?list=all
