Hmm.

I'd say if you want a pure puzzle atmosphere game then The Witness! Its a must try.

Skyrim is the best pick overall, but you've probably played it already.

Both Horizon games.

Outer Wilds

Red Dead 2

Ghost Recon Wildlands

Assassins Creed Black

Riders Republic and Steep.

(My favourite game) Dragon's Dogma: Dark Arisen.

These are all relatively open-world games and do require some time playing though! If you want some not as big games.. then I'd say

Journey

Flower

Proteus

Spirit of the North

Ico (personal favourite)

Shadow of the Colossus (still quite big)

The Last Guardian

Slimer Rancher

Feather

Subnautica

Grow Home

Gravity Rush

Abzu

Steep

Rime

Bully

Rebel Galaxy

Haven and Journey to the Savage Planet are both interesting picks, but they're genuinely fun to just play.

Edit: on phone, sorry for weird layout.

Yeah same aswell, I mainly play games like Horizon Forbidden West, Elden Ring etc. Just to get great screenshots, but I do love chilling in areas and listening to all the games sounds too! Becomes a different game in a way.

This game makes men sad.

I just play everything on the hardest difficulty now, so it'll make me want to complete it and feel that YEAH SCREW YOU GAME! pride.
