I loved looking up at the sky in Oblivion, it was so immersive. Fallout 3 was just.... stars. I cant wait to see Skyrim's night sky, perhaps even a northern lights phenomenon on the new engine. It's going to be awesome.

Yea, my favorite thing on the night was to cast fireballs up in tha air and see them dissapear in the dark. Loved that.

Does anyone know what the giant planets name is?

Those are the two moons, Masser and Secunda.

yeah it was awesome.

Something that interests/bothers me is how almost all views of the sky are a very overbright yellow. It's either completely cloudy, or has an unnaturally strong yellow glow behind the clouds.. only two quick shots showed a "normal" blue sky in the trailer.

Skyrim is basically "winterland" and the sky is different in the winter.
