Found an excellent site for the development of tech trees, Projects and just technology related things for NESing in general. I highly recommend this site gets posted somewhere where it can be found easy. http://www.indianchild.com/inventions.htm


Joining
*Any player can join. Every player that joins must create a family. Every player will choose if to play between 1 and 3 characters.
*If you choose to play only one character then you will play the head of your family.
*If you choose to play two characters then you must play the head of your family and one family member of your choice. It doesn’t have to be the heir but it does have to be a male.
*If you choose to play three characters then you must play the head of your family, you must choose one character from your family (doesn’t have to be heir, must be male) and you can choose one character from any other family (on a first come first serve basis – first to want it get it, unless the player who made that family wants it in which case he gets the man).
*Remember, each character has a DIFFERENT personality! If you cannot see yourself playing as 3 or 2 different people please only play as one!
*You get to choose the first traits of your characters, but only under my supervision. For every 3 good traits you will have to have 2 bad ones.
*You cannot switch characters. Only if one dies you may switch it.
*You may play heirs to other families but only if your own heir is also played by another player (preferably the player who’s heir you control or some kind of mixed players controlling each other’s heirs). This will bring much needed variety to families as players switch families they hold as time passes. Remember your family isn’t the basis of your game, your characters are.
My poor neighbours its 10 to midnight here.... 
Well I don't want players to control their families. Families don't always stand behind their leader. A son may assassinate his father and other brothers in order to rule... One can also be bribed...
But this remain to be thought about. Do families or personals matter more.

If your family survives there is more of a chance your DNA or some of it at least will spread. Humans are weak creatures alone...
