Hi there,
I just read a post about sleeping in game and how it may effect your stats. However this is not about sleeping but about the nights and lighting in general. I played skyrim and I was really uncomfortable with their solution. I really like the idea to have realistic, dark and therefore dangerous nights. This would also add up with the sleeping part, as you had to stay home and sleep at night or otherwise you would have to use a torch or see nothing. Also the Caves and other dark places should be dark, if there is no lightsource. I mean, why would you implement torches etc. (seen in the trailer), if there was no need for them. Exploring a dark place is never as interesting or scary, if it’s actually brightly lighten.
