I was thisclose to pre-ordering Supernatural along with getting Pets and Showtime - the only thing that stopped me was the fact that I'll be getting a $50 gift card soon from Amazon, so I may as well save it for this. Besides, I won't be installing Pets and Showtime until I finish (or get close to finishing) my dynasty.
This will likely be the one and only expansion pack that I pre-order as I already have the perfect family for it, even if they were generated before the announcement - they were meant to play with photography and inventing, but mom would make the perfect fairy and the inventor dad could very easily dabble in witchcraft...I think their daughter will remain a norm for now though, and perhaps they'll get a werewolf for a roommate (and/or a future spouse, hehe). All three of them will definitely be leaving Twinbrook for Moonlight Falls, that's for sure.
