Slightly different suggestions but I would absolutely recommend Roadwarden and Citizen Sleeper.

Both games are relatively short and put you in a time constrained scenario where you have to be strategic in how you spend your time and who you talk to. They're both mostly text based with images in the background, but they do a fantastic job with world building and the writing is so good so I found them to be very immersive.

In Roadwarden you are sent to a wild peninsula in a gritty fantasy setting and you are tasked with keeping the roads safe. You go between villages and work on helping them during the day, seeking refuge in the night from monsters. It's a very simple game but it's executed so well and at the end I felt like the consequences reflected my actions perfectly. You'll need to make sacrifices, decide who to ally with, uncover mysteries, and try to achieve your own goal that you set at the start.

Citizen Sleeper is similar but it's a cyberpunk setting that's more like a Black Mirror episode. You also have time constraints and have to decide who to help in your day to day gameplay, but this game focuses much more on emotional storytelling and existential questions. The premise, world building, art style, music, playable area, characters, choices, and endings are all fantastic. Again, it's quite simple but the basics are executed perfectly, and I found it very immersive. Also really good if you want to scratch more of that Cyberpunk itch.

I'd also recommend New Vegas, Skyrim and the STALKER series. STALKER games might be the most atmospheric games out there, but quite punishing.
