Differences in the family tree Challenge

I think it's pretty obvious, but I like challenges. I currently have four on going right now, and I pretty much play all of them regularly. Except the family man challenge, truthfully. But that's still three challenges to play! I found this one tonight. And although I don't think I'll find myself doing it, I like the different scenarios its gives you. But it's a little too structured for my liken. With that being said, I'll probably try it one day. Or incorporate some of it into a random legacy. Either way, I wanna keep following this, especially after they update it for supernatural!. Check it out here: http://angelofafallen.livejournal.com/818.html?thread=3378
