If I can use any gun I want, use any medical supplies like a physician, pour concrete like a pro and murder other evil survivors with glee...
...why don't the damn cars work?
Sometimes it seems you guys pick and choose which rules of magic you want to abide by on a whim.
Let's use the current rules of game logic--gasoline is rendered impotent at this point according to the logical expiration date set on it. According to this line of logic, antibiotics go out of date after 1 year, so they should be out as well (or at the very latest a few weeks after the game starts).
There are ways of healing outside of items--I haven't used a med kit in months, and only recently because a firebomb went off in Dave's face (the poor guy). Just sit tight. You'll heal. Again, this is another interesting game logic vs. game logic contradiction, because some of the splash pages mention the tiniest wound potentially being lethal.
I think we should all agree that ALL of our ideas of logic are sound, and it's the developer's choice that sets the rules of physics and chemistry in the game world. Nobody's ideas are stupid, wrong, or illogical until the developers rule a suggestion out. Also, remember that, when you say someone's suggestion is not 'serious,' take a step back and look at the fact that 1) we're discussing a game and 2) there are zombies in it.
