Pff, you don't sparkle, what's the point of becoming a vampire ?
Cheap twilight jokes aside, I was thinking about it until I realized how much better the game looks during daylight and that exploring Skyrim at night would make me miss quite a bit of lovely sights.
Changing the topic a bit: who here loves shooting a bow in this game ?

Melee combat is fun and can look great, with all the special death animations, decapitations etc.. but It simply cannot be compared to the satisfaction one gets after clearing out a bandit camp from afar only to come and see all 14 of the 14 arrows shot are sticking out of the dead bandits head. It's no bf3 sniping, but it requires more skill than bashing someone with a sword repeatedly.
