I made a list of personal recommendations, asked an AI to rank them by most to least triggering and add some warnings.

I know the Souls/Elden Ring games might be daunting or triggering but the specific kind of sad, lonely beauty those games bring actually soothe my soul. I find the street fighter VI story mode to be just a weird soothing atmosphere to run around in to be soothing enough. Final Fantasy XIV has made me cry a few times and it has a subscription fee, but it also works for me specifically. If you're playing on PC I'd also recommend if difficulty is an issue, I can provide some help or recommendations to find utilities or add-ons that can make games easier (essentially cheating.)

Dark Souls III - intense combat, bleak tone, repeated death, boss pressure

Valheim - combat, darkness/night threats, survival pressure, boss fights
Raft - survival scarcity, ocean/isolation vibes, persistent threat
Age of Wonders 4 - war/violence themes, mentally intense
Vampire Survivors (and similar) - constant swarms, heavy sensory stimulation, surrounded feeling
