1. It is way more dangerous at night, and if you want it even more dangerous play with a few more vikings in the game.

2. I recently upgraded to a new computer. I will tell you that my old video card made the night look like grey cloudyness. The people I played with kept asking how I was able to see so well. I had no clue what they meant until I got this upgrade, now its like playing in pitch black. Its definatly a video card thing where some allow for brighter nights and others make it total blackout.
