dawn, my tactic is to save up enough for one district, then takeover the rest in one night. The other family will attempt to take one other area, and then you purchase that last one easily. Families disappear fast.
I didn't find the need to lead people. I just ran and hid around corners like how they did it in kid's shows set in high schools. That's what made me laugh.
Really good little game. Got more stress from it than I expected.
