What's that about falling asleep 14 times in a day? What do you mean? That's not how it works...
Anyway, here's Wonderwall:
- Terraria, Minecraft in 2D.
- Dwarf Fortress. It's chill. In a very, ah, neurospecific kind of way.
- Luanti, it's basically open source Minecraft. Moddable in Lua, which is easy enough to pick up.
- Subnautica. Stranded alone on an underwater planet. Not 'relaxing' in the original sense, but there's a sense of discovery few games can replicate. Aside from maybe...
- Outer Wilds. Explore a mini solar system in a rickety spaceship. Everything else would be a spoiler, but you owe it to yourself to play it someday.
