I mainly only like to play fps type games at night, not for creepy effect, but it just feels so much more relaxing during the night.
I also only play three console games at a time, and I always like to play action adventure titles before serious rpg type games kinda as a warm-up. Balancing more than three games can get so confusing, but oddly enough, I never get mixed up with my pc games, even the ones I used a gamepad for.
