Man this question isn't even fair there are so many fantastic soundtracks in gaming I could literally go on for hours about them.

Doom, Mass Effect, Halo, Skyrim, Ratchet and Clank, Assassin's creed(3 especially), Divinity original sin 2, pathfinder: wrath of the righteous, monster hunter, league of legends(all of riot games really), darktide, sonic, payday, witcher, Spiderman, Zelda, cyberpunk, megaman, final fantasy, Devil may cry, metal gear, undertale

that's just what I think of off the top of my head, there could easily be an entire sub just dedicated to the topic
