I wish CA folks would post a bit more often about things that are completely left unexplained in the manual and are not intuitive in the game. Squallor, blinking city stat icons, how to grow a strong family tree, what difference (if any) being a faction heir causes, why cavalry and infantry move at almost the same speed (and where the individual unit speed variables are), what the specific, quantifiable effects of buildings are...blah blah blah...

Sorry, I'm just frustrated with a lot of things in this game, with the fact that they aren't explained in the manual, and that CA folks are not posting often enough to answer some of these major issues in the game.
