Looks totally awesome! 10 times better than the SoU addon.
Skies are cool, but I don't see many people using the 'over the shoulder' camera much--it sounds like it'd be hard to navigate with... And that is the only way to see the skies. BUT, setting up cut-scenes showing off the sky would be VERY cool. I hope they add a wizard to set up camera movements for cut-scenes. Those are VERY hard.
Thanks for the screens! Also, check out
