Speaking of which, based on the numbers, I'm guessing that the zombies did try to infect at least one of us immune folks? I'm curious about that.
Well, when I get home I'll post a play-by-play, but yes, during the very first night one of the zombies chose to infect Imogen, which presented me with a dilemma. As the Nurse, she had access to the vaccines with which she could use to cure herself, but strictly speaking, according to the game rules as I set them up, she was powerless to do anything but turn into a zombie. Unfortunately, it was a situation that I had stupidly not foreseen.
In the end, I gave her the choice to decide what to do, and she chose to cure herself. Unfortunately, that meant she became vulnerable to zombie attack, and the OTHER zombie chose that moment to make a snack out of her brains.
I find it rather interesting that both Imogen and Moirae chose to take the "good" path rather than allow themselves to transform into zombies. Ladies, may I ask what prompted those choices?
I think, if I run another game with similar rules, I'll start with the equivalent of 1 zombie and 2 infected. At first glance, it might seem that the zombies have the edge (since they can, in theory, reproduce exponentially), but in practice, after you factor in the doctor, the nurse, the military vet, the immunes, the survivalist, and the fact that the zombies aren't working together I think the game is actually weighted toward the survivors.
