Some of my favorites include
Minecraft (nostalgia and calming slow paced)
Subnautica 1 and below zero (super calming to listen too and also fit the vibe really well)
No man’s sky (music fits the atmosphere of the game really well)
Payday 2 (very good kinda electronic songs)
Superliminal (very good calming piano)
Boneworks and bonelab (these are absolutely phenomenal like electronic tracks, Michael Wyckoff fucking nailed the sound track for both games and both are perfect)
Red dead redemption 2 (the entire game is perfect and so is the sound track) (haven’t played the first one)
But I swear it’s always the tiny little indie games that hire some guy off of fiverr or something like make some masterpieces.
But what about your gaming computer.
