Torches and Head-Lamps give hardly any visibility and the darkness of the game is enough for me to get really frustrated with. While some developers think it's good to make players wander around in the dark, I think it's just unfair to the players, especially those without perfect eyesight to begin with. There must be more productive ways to show night-time without turning the screen pitch black in the process.
Please just consider making the brightness higher so that people don't have to put up with a really piss-poor night-time experience that almost ruins the entire game. Or at least give the player the option to turn off day/night graphics entirely. That would make things a lot better.
