Phendrana Drifts - Metroid Prime
The atmosphere of Metroid games is why I love the series so much. Metroid Prime was my first(yes I started the series late, but love it more than any other). The point where I knew that this was the best game I ever played(now super metroid is, but that was before I played super metroid) was when I entered the snowy area that was Phendrana Drifts. Snowy areas are always my favorite in Video Games, and I found Phendrana Drifts to top my list in the best snowy area I've been to in a game. It felt so real. To top it off the music fit the area so much. The combination of the snow falling, and the soothing music, along with the colorful weaponry samus has, and the skillful enemies really impressed me. Also to top it off, I got to end it with one of my favorite bosses of the series, Thardus.
