Mine is the Bloom from Torment: Tides of Numenera. I love the fleshy bits. I love the everyday gruesome horror becoming an everyday thing for the people who live there. I love the literally organic surroundings. It’s just by far my favorite location in any game ever. :)
Mine is the tournament boss level from path of exile. Can’t remember the name of the boss but the whole level has this epic music and feel to it
Daresso, King of Swords, music definitely make it 100 times better, though that level is also cool by itself.
