I'm especially keep to fill in any ???'s. Also, i'm unsure about the cumulative effects of bonuses, e.g. If i build Town Watch + Town Guard do i end up with +20 Happiness in total or just +10 Happiness from the Town Guard? Which buildings cancel the effects of their predecessors, and which add to the effects?

Also, for some effects it is unclear what units will gain the bonus, e.g. Acumen and Command bonuses : is it all generals, or just Kings/Heirs?

And, i'm also unsure about valour bonuses on troops for upgrades of, say, bowyers etc. I've read in some places that higher levels of bowyers will give valour upgrades to units produced. I assume if this exists it will only effect units of the appropriate type. Also, will a Master Bowyer give a bonus to Regular Arbalesters, but not to Pavise Arbalesters, since the regulars only require a Bowyers Guild, but the Pavise require the Master Bowyer?
