How about the idea of an ingame camcorder or camera to take pictures or videos of the stuff you're doing. You would have to equip it as a physical camera in your hands with its own interface/controls. It could require batteries and a tape or memory card and when someone finds your dead body they could watch the tapes back and see what you've done! It would allow completely ingame survival stories and add a whole lot more fun when near endgame status. You could also use it as a flashlight and a kind of night vision device to scout around but with the disadvantage of having to lower your weapon. what do you think?
