Why Greater Poland is ruled by someone called Dobiesław Chościsko, who is an obviously randomly generated character, while according to many sources it was then ruled by a semi-legendary Popielid dynasty (Probably Leszko II or Leszko III)? Its better to have a legendary ruler in game that actually exists atleast on paper in real life, than a completely random character. It seriously looks like Paradox didnt do much research on such places for that start date and just added random people.
