Been playing Skyrim for about 45 hours now and aside from a few niggles (most quests I've found can only play out in one particular way, etc) I'm really enjoying it!
I do have a question though - has anyone found a real, practical use for night vision yet? As a Kahjiit Vampire Assassin I have night vision powers coming out the wazoo, but I haven't yet found a single place in the game dark enough to need it. Even the darkest and most subterranean of caves still has enough ambient light to see the environment and enemies by with no problems. Similarly, I have used a single torch so far, and I used them constantly in Oblivion.
If anything, Night Vision is more of an annoyance than a useful ability. For example, using embrace of shadows gives me 180 seconds of invisibility and night vision, but while I may end up cancelling the invisibility after a few seconds when I backstab someone or open a door, the super washed out effect of Night Vision continues on for what feels like an age, making it harder to see detail in the game world.
As it stands, a detect life type spell in NV's place would be far more useful.
Thanks.
