I must agree with Quadalpha. By itself, perhaps that could be an interesting idea for a game (I'm sure there is probably some game akin to it, not necessarily in the same time period though), but it is simply not Total War. I do not believe I have to restate his point; Total War is, at its core, a grand strategy game. Not a "family rising to power" simulator. It is made for controlling a faction, not a person, and many factions do still have to start from humble beginnings.

The Total War formula has worked thus far, and in all honesty it has been changed enough each time to keep it fresh. I'm perfectly happy with it as it is, and would rather they put more time into improving it rather than creating some small-scale unrealistic political simulator.
