I didn't realize at first when I started this challenge that this was posted before the Vampires pack, but this is still a well thought out challenge and it's still a nice template to follow.
I may have bent the rules in a few places, to fit with the Vampires pack mechanics, and also I've been playing with a mod that allows for lethal vampire draining, so I've been doing that instead of locking sims in rooms. Apart from that I've tried to stay true to these guidelines you've laid out. It's been fun so far :smiley:
