Dishonered, the drunken sailor cover goose bumbs still after all those years.

Civilisation IVs Baba Yetu. Still gives me chills. I’ve seen it performed by a small choir and is just as good. https://youtu.be/IJiHDmyhE1A

Original Minecraft and Eve Online

I can't believe no one has said Halo/Halo 2

Everything by Grant Kirkhope is great shout out to the Banjo-Kazooie and Banjo-Tooie osts, also Skies of Arcadia

Ape Escape goes hard. It's not just the nostalgia.

• Disco Elysium introduced me to Sea Power, who have a bunch of cool albums.
• Outer Wilds - I think of the main theme every once in a while and remember all the awesome stuff in that game.

Thomas was alone has a great soundtrack imo.
