This seem like a very interesting challenge which i would like to try out but got some doubts need to clear off first.
1) If let say Adam and Eve had 3 kids so after they grow up and married do I have to control one of them to continue the legacy?? As Adam and Eve eventually will die off. And I know there must be 1 family to be left in old house however if that family member die then i need to move another into the old house? Or i can control any one of them as long as they are from Adam and Eve bloodline?
3) For the start, the world only have a house with Adam and Eve and nothing else right? I as read then it can have a general store?
