I really enjoy the new game pack and its really neat to actually see in the relationship panel who turned your sim. So I came up with this "Bloodlinetree" idea and I now want to know is that even possible?
I like playing legacies and generations and in my opinion the vampires deserve that too.
That sounds like something I would have done if I played the vampires (I just haven't yet). I REALLY like that idea! I get bored if I'm not doing something like that.
If there isn't a way through the game, you can do it yourself, though. There are free Genealogy downloads. MC Command Center says it has GEDCOM to transfer. I started mine on a site called TribalPages.com (it's free) before I was reminded of GEDCOM if that might interest you.
I just made sure I labeled it for a game so people who search names know that it's not real (I used to be into Genealogy, it's important they know that).
Best of luck with it and thank you for the great idea!
