I've always enjoyed the Lost World level in Sonic Adventure for just how... haunted and abandoned it feels. It's also home to the most atmospheric music in the entire game. Say what you will about Adventure, but I find it to be a charming game with loads of character that often gets overshadowed by Sonic Adventure 2; SA2 always gets put on "best Sonic games" lists, and SA1 always appears on "worst Sonic games" lists, which is unfair. I feel like this level, and this game as a whole, deserves a little more love.
