Agreed. This is a question of challenge.
I've long argued that our avatars in games should get tired, sick, and age. For example, if you take a gun shot, your character/game should be unavailable to you for 1-2 months of real time for recovery and physical rehabilitation. A sword cut should result in tetanus or possibly septicemia, the blades employed in most of these settings are filthy. Any serious wound or violent confrontation should have a chance of resulting in PTSD, which paralyzes your character during recurrences of these events. In addition you should have to eat, sleep and defecate in games, and your character should not respond to input commands during these times, leaving you vulnerable.
Some people may find these challenges extreme, but some people are pussies and like to complain. After all, challenges are NEVER at cross purposes with fun.
