Finally got it, I'm a bit bumped...

Nothing new, even some serious errors in it. (mangonel and trebuchet switched)
Noting on how to acquire v&v
Nothing on generals (and what command/dread and stuff does..)

One nice thing, about speed,

if a unit has a march speed of 6, means 6km/h (x 0.28 = 1.68m/s)
running 12 -- 12 km/h

also princesses (decrease loyalty) help spies in revolts, as do cardinals/bishops help spies in other religion provinces to revolt.
