I could never understand how anyone became emotionally attached from the "gowing up" vault sequence in Fallout 3:

agreed, I couldn't care less about what happened to my Dad.
game was just boring so I didn't play it.

edit: to clarify - the whole part was just too quick and there was nothing to make me feel like I was growing up and making a connection.
In meantime I've become a dad so I might give it another shot.
