Other than annoying the everliving crap out of me because I have to turn it back on constantly, I don't see a point in putting a 60 second time limit on this power. Why they couldn't just have it toggle on and off with no restriction on time used is beyond me.

Other than that I am glad they chose a better color than makinhg everything blue, as it was in Oblivion. I would love to be able to enchant Night Eye or find it on gear already enchanted. Another example of Bethesda cutting corners and features.

Skyrim nights are a joke, the first time playing Skyrim i was in some swamp and it got a little bit dark, i thought it was just creepy misty swamp weather.. turns out to be night..

I never ever ever had to use nighteye, caves are extremely well lit
There is an mod to fix the problem btw.
